A little late to the radial party, but I put up a dx classic with 21 3 meter long radials that were placed 180 degrees facing north ( the antenna was up against a fence). And I worked all of South America, South Pacific, Antarctica, South Africa on 100w . Half the time, my dogs would turn my radial field into a spaghetti bowl and I wouldn't even know it! Callum is right as always, just get them on the dirt and hit that tx button.

Good work!!!

Thank you Callum!!!! Now my head won’t explode from overthinking this 🤣🤣

[@g4lmn-ron401]

With my Signature 9 I put 24 radials out in a rough circle, they are each 3 metres long (mostly). Works really well on all bands.

[@J0HN3]

Just bought a classic and also did 24 radials, 4 per lug, 6 lugs, at 3meters length. Excellent results. SWRs were near perfect across the board from 70cm up thru 40m.

[@W7AWE]

Callum … Absolutely true. I have the expedition with 10, 12, 17, 20, 30 & 40/15 m bands. My radials are “alligator clips” with 4 - 12’ (old money) wire bundles. I clip the 4 wire bundles on the base plate for faster deployment and it gives me a 16 wire radial field. I use it for POTA activations and have deployed the radial field all in a 90 degree area of the base for a couple activations. The radial field was pointed towards the west and I had no problem on SSB making contacts along the east coast and Europe for a contest. I live in Tucson, Arizona for reference. It really proved to me the position of the radial field isn’t all that important. Thank you for another great video. Keep them coming!

[@bigmartin]

The alligator clips is a fantastic idea, cheers!

[@marlomontanaro3233]

Thank you for saying this Callum!!! Finally. The bottom line is the base of a ground mounted vertical is a current node. More metal closer to the base of the antenna will allow for better conductivity at that point... more radials.... The current node is where the antenna radiates from!

[@contactmiller]

I used 17 radials that are 17 feet long. A few are a little shorter due to the house. I had 250 feet of dog fence wire and used almost all of it. Seems to work pretty good. The earth diffuses the ground plane so you don't need to worry about tuning. If your vertical is elevated then the radials need to be tuned to each band you are planning to use and measured exactly.

I'm FCC certified several times over. I could design a perfect antenna to talk to Moscow at high noon from Nebraska. I don't have to, I don't want to, and I can wait until 1am where the ionosphere let me anyway with any good antenna. People, including me, get hung up on the BEST thing we can design or make. But it realistically will never EVER come up to max spec. Be it radio or art, you have to eventually say "this is the best I can make, in the time I can make it in"

Hi Cal, my Classic has been up nearly 4 years now with 6x4 bundles of radials cut into the grass delivering dx into Antarctica, Hawaii, Alaska VK & ZL. All radial lengths as recommended by you and the added bonus is unlike chicken wire (in the 70's) they will not rot over time. 😂 Great video by the way .

Very nice - follows the results others give on PRACTICAL advice, not schoolbook theory. Thanks Callum (I have found the same thing with my old 5BTV - still 1~2 S units less than the 80M OCF, but it still does low angle radiation needed here and there)

[@VE7IRR]

I have a Classic and 25 x 3.5 meter radials configured in a semi circle (180 degrees) as I have mounted the antenna against the fence in the back yard here in the West Coast of Canada. I did this to eliminate the need for guy wires. I get outstanding results in all compass points. I thought I would have troubles in the direction, but such is definitely not the case. As Callum says, just get the wire on the ground! Cheers from VE7IRR.

[@DXCommanderHQ]

Nice one Ron.

[@EmJayArr]

All true. For my scrap 20m vertical contest submission, I had enough for 21 radials that were only about 1/12th wavelength long, for a total of 1.75 wavelengths of radials. It worked great!

[@DXCommanderHQ]

Brilliant!

[@Dave-VK5PL]

in the process of putting down about 32 x 3m radials for my vertical, so this has confirmed that my doubts were not neccessary.

[@ZeroHarry]

Lord Callum, good honest point of view. Personally, I’ve found that if you pour your warm beer over the radials, it will vastly improve signal propagation. See here in Australia we don’t drink warm beer so it’s a no brainer during summer. Try it for yourself, put up a sign near your ground radials during your next BBQ. Pour warm beer here!

[@DXCommanderHQ]

Next time! LOL

[@johnpawlicki1184]

One year for my portable antenna I wound a coil on a wire with my 20 foot crappie pole. Used a 9:1 unun and various lengths of wire radials whateven worked. Carried several wire lengths and tuned the wires. Worked fine. Much better than a base loaded vertical. 73.

[@dondonaldson1684]

A hand-held (aka handie-talkie) has no radials except for the iron in the blood of its holder and it works fine. Some radials is easily enough on a vertical. Great video Cal!!!

[@NebukedNezzer]

there was a ham in texas w5pyt. he knew and shared a lot. how to tell if your antenna is efficient. with a measured power like 5 watts. read the antenna current with a current meter(make one). when you stop getting improvements in antenna current stop adding ground radials.

[@RF_Burns]

I doubled my radials and I definitely noticed a difference... that I was 40 quid out of pocket, and I had backache all weekend!

[@DXCommanderHQ]

You noticed..? OK, great. Poor back though! :)

[@RF_Burns]

@@DXCommanderHQ No, going from 100 meters to 200 meters I noticed no difference to signal strength... but I certainly noticed the backache!

[@ke4edd]

I like this advice. My QRZ page shows the antenna I've used to make contacts in 12 countries not counting my own and 17 United States. At the time, it was a not-quite-quarter-wave wire pulled from the ground into a tree. The "radials" was a ground rod driven 8 feet into the dirt. I'm told by a fellow on QRZ forums that there's a lot of loss into the ground this way, but I made it a quarter of the way around the world with 20 watts peak envelope. Granted the other guy had a 100 element stacked super yagi pointed right at me but still... Point is, that wire-and-ground-rod got me on the air and got me the majority of the contacts I've made in the two months I've been on HF. I now am adding radials out of #24 AWG Ethernet cable wire and replaced the 8 foot ground rod with one about 3 1/2 feet long. Should have less ground loss, but I haven't had this new setup long enough to make a determination that it performs any better... but I'm confident it will prove itself.

[@DXCommanderHQ]

OK, so that grounbd rod will do nothing really. Disconnect it temporarily and do a test with a local friend. EVERYTHING works, it's just how well you want it. You could probably double your effective radiated power with some short radials.

[@migalito1955]

Last summer I neededed a quick bamboo vertical for 20 meters using speaker wire as the radiator. I did not have enough wire for radials, but had two good sized pieces of wire fabric with 1/4 inch grids. Sat the vertical over the fabric and connected the shield to it and wala we had a perfectly functional antenna for the needed moment.

[@DXCommanderHQ]

Nice work!

[@DavidMitchell79]

I have been reading on the vertical antenna and ground system topic. If I understand/comprehend correctly, the radials merely decrease losses in the ground image (acts as a dipole, vertical radiates and a mirror image in the ground makes up the other half of the dipole) by reducing the resistance of the ground. "The ground acts as a lossy capacitor" is how they describe it. That being said, the radials would counteract that by 1. Reducing the resistance and 2. By adding inductance to counteract the capacitance of the soil. I could have misunderstood my reading. But it does seem to explain why more of the shorter radials would work. Thanks for the vids, Callum. You are a true "Elmer" and a ham couldn't ask for a better mentor (or "experi-mentor")!

[@DXCommanderHQ]

I suppose that's the complex way of looking at it, yes :)

[@oldbassist60]

I could not agree with you more. You are 150% spot on.

[@dandypoint]

Good info. I thought I would add my experience here. On 160 meters, since 2001, I have used a 165 to 180 foot inverted L with usually 2 radials. Sometimes none (2014-2017) and occasionally three (2013-2014). I worked over 700 QSOs in 160 meter contests with no radials in 2014 and 2017. I worked over 800 with I think three radials but it may have been two in 2013. I definitely worked 874 QSOs with only two radials in 2012. At my current QTH, I have a ground rod at the base of my 160 meter inverted L and always one, sometimes two radials. Good enough for 450 to 600 plus QSOs in most 160 contests since 2019 without many hours of effort. I do also hold 160 meter DXCC with the inverted L and it’s “substandard radial” system! So the antennas with a minimal ground system do work and pretty good at that. The ground or radial system make up half of the antenna in antenna systems where they are necessary. A simple ground rod should in most cases be significantly less effective than having radials. I am not sure you can always tell much difference. The quality of the ground out in front of the vertical, about which you can do absolutely nothing to fix, is a major factor in vertical performance. Reducing ground loses at the base of the vertical is within the things you can do. We do that with a “good ground”. Whatever that means. Sometimes things are so good that a ground rod by itself works really good. Sometimes only a few radials seem to be enough. Sometimes we don’t know when to stop. In any case it’s always a case of diminishing returns. However, on 160 meters I have never used more that three radials for one reason or another! 73 de N4DJ

[@nvrumi]

Callum, I saw you talk about this a couple-three years ago. I got Severns' papers and read them all. It is good stuff and he does the technicals as well as the practicals. At that time I quit worrying about the ground field and just made sure I had enough wires on the ground (16). I don't have a DX Commander (yet), but use this with a WRC system. I plan on building a set for my Chameleon MPAS 2.0 for vertical deployment. Now I need to see if the Signature 9 antennas are in stock. 😛

I built a PAC-12 antenna and use 4 radials. I live on the second floor of my apartment and have a small deck. The wires droop down over the deck, so far the downstairs neighbor hasn't complained. I also built 4 loading coils for the radials and I think it might have helped at least with SWR. The apartment complex is a little electrically noisy so I haven't try making contracts yet. I also built a AM broadcast coil compatible with my PAC-12 and I can get it to tune to 1.610MHz at 1.2 SWR (checked with my VNA) for my part 15 transmitter. 73 de David KEØPBI :3

I have a 36 foot vertical (in 5 sections that screw together) that I used when I lived in Cameroon. I had NO radials at all, but it WAS grounded with some serious copper braid to a ground rod and it worked well, in spite of not having radials. It sat on a ledge of the house at about 10 feet off the ground. I used an Icom AT4 with it. I was able to tune it from 160 to 10 meters and used it a lot with good signal reports. Also had a 2 ele Mosley triband at about 60 foot elevation, also well grounded which did quite well in spite of the house being surrounded by houses at higher level than mine, except to the east of my qth. I was in an area probably about 40 ft lower than everything to the west and northwest, but to the east was okay. 73's from ex TJ2US and ex J5UAI, now kb0jqc

Thank you so much for making this video. Funny story, though - I have a Chameleon MPAS 2.0 set up in the vertical mode (~ 22' high with a cap hat half way down - attached to a 500watt 5:1 (I believe) unun, which is then attached to a 1' ground spike for support). It came supplied with a sigle 20' 'counterpoise/radial ... OK - set up in that configuration, the swr (as tested on my RigExpert analyzer) was ~ 2.8 @ 40m, then dropped in a 'parabolic curve' to ~ 1.8 @ 20m, then rose and plateaued ~ 2.5 @15-10m, then rose up past 3@6m. Then, I added 8 x 16' (1/8 lambda @ 40m == 1/4 lambda @ 20m) radials in a 360 degree circle - straight, no bends or overlaps. Guess what - the swr shot up to over 6.3@ 40m, dropped down to 1.5@ 20m, then shot back up to over 3.0 by 10m. Chameleon didn't have any answers as to why this happened, so it looks like I have a 'Radial-Tuned' Vertical Antenna - No Coils Required 🙂

[@DXCommanderHQ]

Apparently Chameleon don't answer many tech questions. So their customers email ME!

[@mikeymouse4629]

@@DXCommanderHQ Subtle ! 🙂 Oh, BTW., you had suggested that I ask Chameleon for a 'far field' plot of their MPAS 2.0 (in the vertical config.) when I was wondering if their 'cap hat' raised or lowered the 'takeoff angle' (required for DX). Well, as I recall, they said that the cap hat should pull the current up the antenna somewhat, but how that would affect the takeoff angle they didn't know, and that it would bee too expensive and not cost effective to create a 'far field' plot. They pointed out that this antenna was meant for man-portability, rapid setup and reliable NVIS-type communication within a few hundred miles. And that it was not meant for DX communications. Fair enough, but I like to experiment and see how I can 'push things'. 🙂 Thank you for all your previous advice on this.

[@mikeoswald8053]

I've put up the DX Commander Classic twice and on opposite ends of the US. Both times I used the radial pattern and lengths suggested by Callum's instructions and the antenna has worked very well. As to the radials "disappearing into the grass", let me give my 2 cents worth. Ground staples are important to allow the radials to lay flat. The staples aren't that expensive; buy some extra at the garden store if need be. Finally don't cut the grass as close as you're used to for a few weeks, raise the cutting height of the mower, especially if your garden/lawn is primarily St. Augustine grass. That type of grass is considered a weed in many states but is common in the southern US. St."A" loves to push back against anything laying upon it, however, if allowed to grow to a 3 1/2-4" blade height the grass will "relax" it's grip on the radial and allow it to sink to the dirt. Adjust the mower height as need be and all is well! AA7MO

I have a small yard.... maybe 3 by 5 meters or so..... and most of the time I've operated I've had around 8 radials in a 90 degree arc (antenna is in corner) and got DXCC, WAS, etc on it... this year due to some issues, I've only got 1 proper radial (most of the radials i placed in lawn have over time been destroyed by mowing, and so have 1 ever-so-slightly above the ground (like an inch) and I've completed 40,30,20 band DXCC and not very far from completing 15,12, 10... bit further on 17 but just has felt I've had really bad luck on timing there and generally has been a harder band for me some reason. So yeah... its doable with less. Never going to compete with big-gun stations, but still getting on the air the priority number one... and its all about getting something that radiates up.

I know it may be counterintuitive.... broadcasters go to great lengths to keep RF current out of the soil, by using ground screens.

[@richblair8543]

Sorry for such an elementary question. But here it is. How does the gauge of wire affect radials? Thanks

[@DXCommanderHQ]

Nope. But good question.

[@richblair8543]

@DXCommanderHQ thank you

[@mi6xgzjon186]

using an x80 vertical i put out 8 counter poise about 1 inch under ground, with 25w i got into usa first time ever but as you say all the counter poise are facing the wrong direction so right there with your video. i cut them all the same length as the vertical ( 5m ) im having to move the x80 soon as the trees are starting to catch the top of it and bend it. should i lift the counterpoises and move them as well or will they still be effective if i run a feed wire from the counterpoise junction point the new x80 position 5m away? great vid thankyou.🤓

[@giulianoggg2035]

Yes great explanation but for me I am getting the 6 BTV next month and I am wondering how to prepare the hole? How deep and what circumference diameter to fill with cement and what type of mast in length and diameter to fix in the ground and size to remain out for holding the 6BTV? Can you help ? thank you

[@DXCommanderHQ]

No idea mate. Go signature 9!! :)

[@fm71450]

Dear Callum, thank you for this clear explanation. Have you considered using metal window screen in lieu of wire radials? Or, have you tried using (aluminum) window screen? If so, please describe what occurred. All the best

[@DXCommanderHQ]

No I haven't. It'll work though.

[@Paul_VK3HN]

Used a 1/4 wave vertical for portable and SOTA with four 1/4 wave radials each wirh banana plug. Often did receive tests by pulling them out one by one. Removing radials #4 and #3 made no discernible difference. Removing #2 was just audible, guessing 2-3 dB. Removing the last one and receiver noise dropped to the floor. As a result I frequently just rolled out one radial. I think it's also known as a counterpoise.

[@DXCommanderHQ]

Yes OK Paul.. I do believe it might be worth cutting your 1/4 in half and putting them in pairs on bananas.. But hey, if it works..

[@Paul_VK3HN]

@@DXCommanderHQ Will try that, thanks Callum. And easier to roll out.

[@Paulio91184]

All this radial stuff is what caused me to run a center fed dipole 😂

[@DXCommanderHQ]

And that. Get it up HIGH.

[@jcvee15]

Thanks for the great video, Callum. I'm probably still over thinking this but if I'm going to cut radials at a given wavelength (e.g. 1/8 wavelength), should they still be cut based on the lowest frequency of the antenna (e.g. 30m for the Rapide)? Thanks, and 73!

[@DXCommanderHQ]

No.. Random works.

[@snakezdewiggle6084]

Never heard of a discone then ! ;)

[@DXCommanderHQ]

For 40m? Yes, the US military still have a working one. Google it.

[@snakezdewiggle6084]

Why would I do that ? ;)

[@RomstarOrion]

I spent bloody years chasing a few dB here and there. I finally realized it just wasn't worth it in almost all cases. Now I am too broken and too old to give a crap unless it really makes a difference.

[@DXCommanderHQ]

Perfect.

[@patriot9455]

Trying for perfection leads to headaches and stomach problems. Time spent in hospital is time away from enjoyment

[@tcogm]

The best advice in this video: Put the copper down. That’s it. That’s what I did and I’ve worked the world using scrap ethernet cable as radials. Measure the radiating element and put the radials down!

[@HowToHam_Tom]

Sir- I have just cut up a bunch of Cat5 cable to make radials, on the recommendation of another YT guy. Did you pull yours out of the sheath and then spread completely, or bundle at points or exactly how did you deploy yours? Thanks. Tom

[@tcogm]

@@HowToHam_Tom I took the four twisted pairs out of the sheath but I didn’t untwist the pairs because that seemed to be more trouble than it was worth. The 5m pairs make an X and the 3m pairs make a + so they are all spread out evenly around the base. I used some ground staples to hold them flat to the ground since they like to coil back up on their own.

[@HowToHam_Tom]

@@tcogm well between this video and your much-appreciated reply, I can sleep at night and finish what I started. Already made 8 sets (originally for 2 simple 10m antennas. Now I’ll use all on the DXC that I am buying today (as soon as the Easter Special Sale goes live in a few hours) and I will putz away with it and be happy with whatever results I get. I don’t know why I worry. My current antenna is a home-brew job… think “shower curtain rod) which is tunable bu sliding the section up or down and hose-clamp tightening. It has 4 radials attached I put out in a + form. This jankapotamus was given to me by my Elmer. I pounded the stake-mount into the ground. It tunes to 1.2-1.7 on the tech portion of 10m and my FT-950 does the rest. Total junk and I’ve worked as far as the Czech Republic 100 watts from the gulf coast of Florida. I should be able to hit VK with a real antenna hihi Thanks for the help 73. Tom Waters

[@AlvinMcManus]

With the 80 meter option I have 55.1meters of DX10 wire left for radials. That would be (10) 5.5meter radials or (20) 2.25meter radials. Is that enough?

[@DXCommanderHQ]

Sure.. You can always add more some day.. FOr 80m, if you feel you need more clunk, add about 80m more one day..

[@calvinlong1265]

I really enjoy your videos! Quick question, can you use copper clad aluminum core wire for radials?

[@DXCommanderHQ]

Yes you can! Any wire actually. Literally ANYTHING.

[@UpcomingChris]

I have a a fairly small garden, I may not have 5m to run even one radial, how big of an issue is it if the radials aren't straight, can they loop back on themselves? 90 degree bends in them, zig zag etc, is that something that will hurt the performance to a noticeable level?

[@DXCommanderHQ]

Don't come back.. Just put more shorter ones down.

[@richie4540]

Whats the least number of radials can you use?

[@DXCommanderHQ]

I started mny career with 4. 8 better and 16 means you are starting to eat into your wallet and not the gain. ALternatively, double the number of radials and cut them in half. Same amount of wire, no change in gain.

[@TheREALJosephTurner]

Have you ever experimented with the distance between the radial plate and driven plate, or the distance between the ground and the radial plate? I've always wondered if those mattered or not. I've also wondered if one were to use a loop-on-the-ground receive antenna, if there would be any concerns about the distance between it and the radials of a vertical. These are the kinds of things that pop into my head when I'm bored- I may need therapy. 😂

[@DXCommanderHQ]

It will eventually matter because if you think about it, each element needs to be near the feedpoint.. STretching it out means we are connecting the element firther up the "master" element and eventually it won't work as planned. Good question.

[@skoda8761]

My antenne is elevated flat roof 25 mtrs high, then i must have good length for good SWR

[@DXCommanderHQ]

Yeah.. read the title :)

[@sv4rin]

Greetings from Greece, my dearest friend. Do I still need radials if I setup my vertical antenna at the beach , almost inside the water ? 73 de SV4RIN

[@DXCommanderHQ]

Erm.. Well I would, say 4 or 8 short ones.

[@richardmillican7733]

People with a fear of spiders won't like this video! 😂

[@DXCommanderHQ]

Oh yes!

[@zs1ml-mariuslubbe505]

I see no difference between 1/4 wave radial field an a bunch of 2,5m radials. It just works.

[@DXCommanderHQ]

Same.

[@acestudioscouk-Ace-G0ACE]

Overthink things? That's dangerous! Never have more thoughts than radials... and 16 radials is enough to talk to the world, it's wife and pet dog. LOL 😆🤣

[@bobr6555]

How would using gal strap say 1 inch wide go? Could you get the same result with just two or three as you would with a bunch of wires?

[@DXCommanderHQ]

Erm.. Probably. You would have to try it. Essentially, you would be 3 x radials.

[@unclemikeyplays]

I'm a n00b. I have a kit with 3 very long (33', 10m) radials. Am I better off cutting them up into lots of smaller ones? Is there anything gained by sort of...running them in spirals or other patterns that meant they cover more ground closer to the antenna? Is it all just magic? 😀 I'm not sweating it a lot, but I am curious!

[@DXCommanderHQ]

Chances are, lots of 6 ft radials in a STRAIGHT line will be better.

[@unclemikeyplays]

@@DXCommanderHQ Thank you!

[@skoda8761]

What about SWR Cal?

[@DXCommanderHQ]

You will still get fine SWR.

[@davidKD9WTA]

What if you need to bury them a inch or so?

[@DXCommanderHQ]

I would not physically bury them. Too deep and it won't work. I use "biodegradable radial pins" which hold them tight to the ground and within a week or so, they've gone.

[@9z4bm]

Have you ever modelled the DXC at a height of lets say 30ft , using radials , but instead of 1/4 wave use 1/8 wave ? I am thinking i cam make the radials from aluminium tubing .

[@DXCommanderHQ]

Well, you could do. It would be HUGE and unless you can get to at least half a wavelength, it's just not worth it. Actually I have a video coming out toying with this idea..
