No Radial Vertical Multiband HF Antenna - Should You Buy It? Watch This First

[@kirk1618]

I bought one and did some mods to it. I wanted to use it for my digital mode radio at no more than 75 W. Worked great. One day I noticed some stringy stuff hanging on the shed below the antenna. I realized it was the balun box that had melted. I changed the balun to a 9:1 rated for 2.5 KW, but never transmitted more than 75 W. To accommodate the lager balun, I remove the old box at the bottom and replace it with a larger box and provided screened 1 1/4" vent holes. Wow, what antenna for the money. I moved and bought a Titan Gap for my new backyard. I love my Titan, but I'd go right back to this antenna if something were to happen to the Titan. I've thought about making a with mount and using it for POTA, if I can ever get motivated. Worth the money, and the upgrade cost, in my book.

[@ivandubinsky1857]

I had the MFJ version of this antenna. It worked semi ok on 20 meters and above. I might have made a contact or two on 30 meters. It was basically useless on 40 and 80 meters. It was, however, not a bad antenna for shortwave listening. After about one year, the mount failed from metal fatigue and the whole thing came down in a windstorm. You can save yourself a pile of money and put up a simple random wire made out of speaker wire and get much better performance to boot.

@@1OFGODSOWN I use a DX Commander Classic telescoping pole with a 29 ft random wire, 9:1 unun and 1:1 unun as a choke. I don't have trees close to my home either. I got this idea from Walt on this CoastalWavesWires channel that we are on. Walt has many ideas on how to set up wire antennas on different DX Commander poles without using trees. He also uses Squid Poles to hang random wires, too. Check it out. I got my first DX contact from Texas on this setup. I live in north central Georgia. I hope this helps. 73s.

Nice shirt! I was the Chief Engineer at WLS and the company LMA’d the Loop for a few years. Sad that it’s gone now. I have just put up the aluminum version of that antenna with an auto-tuner at the base, and I have radials under it. No vertical will work well without radials. Anyone who believes that doesn’t understand the basics of antennas. Just because you have good SWR doesn’t mean it’s actually radiating a good signal. Even a dummy load radiates to some degree, but you won’t be working many people on it. I can’t speak for this add-on radials, but mine are buried in my yard.

[@COASTALWAVESWIRES]

Exactly, that was pretty much the point I was making about my performing because of the metal roof under it. Thanks for watching and commenting.

[@samallan6616]

Most chain-link fences make exceptional radial systems for vertical antennas regardless of band. The longer the better, especially on the low bands. The older fences which have horizontal pipes on top work the best. Just make sure to bond the horizontal pipes to the posts in the ground with good quality braid. I have used mobile antennas, 6BTV's, Hy-Gain's, and others, including a home-made 75/40 meter vertical. With a little tuning, all worked fantastic!

[@wmlangton]

Hey Walt! I have the Sigma, aluminum version of this and use it as a portable antenna for my motorhome. I utilize a couple of different mounting options - ground mounted on a bicycle repair stand that I have modified to bolt the bracket on and a flag pole mount on the rear of my coach that gets it about 14' up in the air at the base. I have had outstanding luck with it as I travel around the western US. I've worked all over North & South America, Asia, the South Pacific and even a couple of openings into Europe. I regularly check into an 75m net in the evenings as well. All of this barefoot on a IC-7300 or my old Yaesu FT-100 mobile, all band rig. While on the road in the coach, I don't have the luxury of a fixed antenna. This gives me the ability to get on the air, have some fun and provides a quick and easy way to deploy an antenna, even in a limited space like a campsite! (I also carry two 9:1, EFRW - 1 50' and 1 84' as well as a ZSKBKW dipole with a 40'' extendable fiberglass pole in the MH for those times when I have more room to play with) Keep up the good reviews!

I have had the aluminium version for 2 years and it's great. I am 118 metres above sea level and have had brilliant results.

Hi Walt, it’s a good review. If you can live only with 20 meters, a delta loop antenna can also do wonders. It has low noise floor and its gain is better than a vertical, it’s not hard to build one with wire and a 4:1 unun.

I was using my aluminum version at 50 watts and the unun melted through the plastic box. That seems to be the weak link for these antennas.

[@indianashortwave]

Have used an Antron A99 for years mostly on 10 meters and 11 meter CB band but also have tuned it up on 12, 15 and 17. Longest contacts for me using that antenna and those bands was 10 meters to Australia and New Zealand countless times along with Johannesburg, South Africa on 17 meters during 2009 solar minimum along with South America, Russia, Europe, etc. It was best 65 dollars I spent at the time back in 1999 and its still up 24 years later and still works.

[@howardkarse9915]

I just don't see it as a bargain or great antenna. Granted it's a simple install and does not take a lot of space: However, if I am going to need a tuner and another easy to install antenna I have great success using a 9:1 unun with a 41' radiator wire and 25' counterpoise. The end of the radiator wire can be hoisted over a branch or tethered to a lightweight fiberglass mast with total cost under $100. You do give a good review of the good and not so good so WELL DONE on your part, just not my cup of tea.

[@radiotests]

Ironically most guys miss that an aluminum mast itself can be used as an antenna provided you use the correct length for the frequencies. Its even broader on band because b of its size of 1.5 to 2.5 inches. Radials in still required

I have one I bought off eBay, it came from the UK. I run a Xiegu G90 on it, and have worked Australia, New Zealand, Europe, both on SSB and FT8. Interesting thing is, the paper that came with the antenna said that auto tuners will work fine on the harmonically related bands (80-40-20-15-10m) but a manual tuner is required for the WARC bands. I found out this is not so, the great tuner in the G90 works fine on all the bands. Great deal for about $150 (with shipping from UK)

[@kagmich5796]

@COASTALWAVESWIRES Ok I got it perfectly set for the 10 meter band. Make sure the whip is adjusted so the entire length (fiberglass section and whip) is 98". It will cover the entire 10 meter band! I wasn't able to connect it to my radio but my analyzer shows a 1.4:1 SWR across the entire band. By the way the 98" is from the very bottom (of the threads) to the top of the whip.

Even if I get the SWR right I will go back to my MFJ-2220 because of the reception. I'll play with it for a While.

I did not tune my Sigma Version, purchased about 5 years ago. I did make a contact with Australia and Italy from San Diego. Mounted on a vent drain pipe on my deck about 20 feet into the air. I did not "tune" it and to see it costing a couple hundred dollars less than what I paid, it's worth the money now. I think I paid $400 for the Sigma. I just erected a GAPFILLER DX 31ft vertical and the Sigma has taken a back seat.

[@johnnorth9355]

Never buy the x80 aluminum version unless you pot the un-un or better still move it from underneath and seal it in a box (I use a sandwich box). The fibreglass version is not a problem. The extra radials plus pack really does open up 40 and 80 once you have tuned them (the whips can also be used portable like a hamstick) although they are best described as fair not good. I lasted six months with one of these before setting up a long wire as well but still use the x80 which together with a mag loop and the long wire gives me all the QRP performance I need in my small shack . If you are just starting up or even a CB'er then give it a go - it really works. 73 . M7BLC

[@duaneshuster6366]

The A-zon reviews are mixed somd people got good results. I'm a fan of 10 & 17 Do you think that the top whip has to be longer to resonate better I bet on a fense or wires on ground would make it work better especially when ground is wet for 40 . Ok thanks for your input on this antenna 73z

When people take advertising, nearly *any* advertising as being 100% truthful, I think they're usually going to be sorely disappointed. I first learned that lesson when I bought some "Sea Monkeys" from an advertisement in some magazine when I was a kid. I didn't get any "monkeys" at all, "sea" or land-based. The only thing I got were some tiny, almost microscopic brine shrimp! *LOL* I also learned my lesson in 1989 when I had first gotten my Novice Amateur License. I bought one of the _magical verticals_ that (supposedly) covered 80 - 10 meters with "no tuning." All I got were more "Sea Monkeys," just in a vertical configuration. 😆 Actually, that antenna did have radials included, and probably worked better that many of the other multi-band verticals that were/are sold.

[@kagmich5796]

Hey Walt. I upgraded my home shack to the Xeigu VG4 vertical antenna and took the antenna (in this video) down off of my roof. After taking it down I noticed that the fiberglass section that the whip is connected to has 3/8" threads.... 🙂. Im thinking of experimenting with trying this section out on my car mount. Just curious if you have tried this. If not, no worries. I will put a meter on it and let you know where it is resonant but since it doesn't (appear) to have any "coil" section Im thinking it may be perfect for 10 meters. Will keep you posted!

I’ve seen this and similar antennas, and wondered how (or *IF)* they could work. I’ll have to check out those specs. It almost sounds like a *SHORT* vertical *random wire* - perhaps with a 9:1 UNUN attached? That said, I wonder if you could say it’s the _”best”_ antenna for its size, form factor, and cost? IOW, *ALL 3.* I’m sure a simple dipole would work better and be cheaper, but the form factor would be much larger. I’m guessing that it would be more efficient than hamsticks, shortish coil antennas, etc. For my needs, I would *START* with the size constraints, then figure out how to most efficiently use that length. I would *GUESS* that you could design a *trap vertical* for 6-20 meters, then figure out a way to tune 30-80 on it. I remember a very old adage - _”if you want more signal, you gotta stick up more metal”._ 😀 P.S. It’s now $105 on Amazon. P.P.S. I looked at a couple of the _”random wire”_ websites, and the lowest number I could find was *_29 feet._* *73 de AF6AS in **_“DM13”_** land*

I wish I had seen this video before I bought the Sigma Eurocomm version with the 40/80 radial kit. In practice this antenna is a complete waste of space, time and money. It halves my signal and introduces noise where noise on my end fed wire has none. I have the fibreglass version and have tried it on a metal roof, at ground level and on a 7 meter pole. Nothing, nada. It’s not really that good on 20m in any case but on other bands it’s useless. The sick thing is the “branded” version sells for something like US$500 here, I got mine from the UK and it was still not cheap. And it started to rust within days of installation even though I’m a good distance from the sea. Save your money, it’s junk. Great review.

I think the U bracket is perfect, I actually have a wire from my U bracket down to my metal roof

[@DavidS-iw4ei]

I have the XE-80. I have it mounted on a brick wall with 100' coax no radials. 6m-20m tunes and works well. Lets give it a 7 out of 10. On 20m from California. I have worked most of N America with some DX. Would I buy one again, Yes. Easy to install and get working. But it still a sub $150 antenna.

Thanks for sharing!

[@janvelter3253]

I got one ... a HF 360 from Sigma. I live in belgium europe and due to the low radiation angle ... in a circle of 500km ... nogo but every station above 500km away ... 9+ easy. I average make +1000km contacts .... 3000km easly and I had a contact with Brasil too ... about 8000km away. I heard Falkland islands and japan too with this thing and I'm in a enclosed by builings situation over here with the antenna just sticking out above my roof. It's defenetly not a perfect antenna but it's certainly not a dummy load. It works .... and if you are in a compromised situation ... well .... give it a try ;)

[@COASTALWAVESWIRES]

Well said! Thanks for watching

[@davidw460]

Exactly what I have seen too. The antenna has made the difference between radio and no radio.

[@curtismcadams6096]

Can you make a suggestion on what I should get that economical?I'm just living on a toast security.No bedrooms and nothing thank you

[@leos9865]

I have one for about 10 years it's ok. But after it is up for about a year or more you will need gloves if you do anything with it. If not, you will get fiberglass splinters all over your hand.

[@Brenda-jf2pe]

I varnished mine with clear polyurethane several coats! Will not hurt performance and no splinters 🇺🇸😎📡🎙JohnBoyUtah KJ7TBR. 73

[@scottwiseman8015]

Like any fiberglass antenna. Applying a sealer helps, but not foolproof.

[@bradbeard4575]

I have a couple of questions. I’m still unable to find alternatives with housing restrictions, for antenna. With a vertical antenna. I was thinking of mounting it at the end of the house By mounting the vertical hf antenna along the end of the house. I could attach the return coax to the metal roof (the metal roof is 36 ft long). Using an ATU at the radio. Do you see any obvious issues? Would I still use the unun on the antenna with the “radials” attached to the metal roof?

[@bradbeard4575]

Also should add, I’m trying to work 40 meters mostly. But want to use other frequencies as well

[@radiotests]

Harvest, Grabil are pretty much the same Taiwan company that makes really good gear for fair prices. Better than MFJ in the final accounting. Imo You and both know living on Saltwater makes the Vertical shine without ground plain on the conventional sense. You have a perfect conducting groundwave.

[@mdouble100]

Thanks for an honest review

[@ehsnils]

I have a similar antenna, fault #1 - there's no drain hole on the balun so it got waterlogged quickly. And it's more a single band antenna not a multi band. I got my aluminum one tuned for the 15 meter band now and it's doing decent there.

[@wiley2068]

I'm not finding that antenna anywhere online, was there a upgrade?

[@zveck06]

MFJ makes a 17' extendable whip with a loading coil that I use POTA 40 and up. Get that for that metal roof

[@COASTALWAVESWIRES]

I use that setup for portable as well

[@r111k]

I enjoyed this video and another where you built a 20m vertical with speaker wire. I’m curious if you believe this antenna works better on 20 than the home brew speaker wire antenna? I’m thinking this antenna looks easier to setup but I’d rather use whichever option provides the best performance. Thanks!

[@COASTALWAVESWIRES]

Thanks, honestly if you are just looking to work an individual band like 20 meters the home brew antenna for that band will work much better. If you're looking for a multiband antenna and have limited space and options this is a good choice as long as you have a way to tune it with either a built in Automatic Antenna Tuner in your radio or an external one. Hope that answers your question and helps. All the best and 73, Walt

[@WX4CB]

i'm looking for a decent vertical that I can just screw together when i go out to the beach. what you think for this antenna for that job?

[@COASTALWAVESWIRES]

Definitely not the antenna for that, this would be a pain to take apart and put back together. There’s a video on my channel called “Beach Antennas”. Take a look at that.

[@genemitchell8948]

I have the aluminum version ground mounted at 10" with 62 radials in various lengths and make contacts all around the world and my ic7300 tunes every band but 80m Well worth the $109

how did you attach your radials?????

Yes radio was so great then!!!

[@NickkoG]

Good morning, and thanks for your video. In another video, you say that vertical antenna is fine for portable. Is this antenne performe less than the other you show in your video 10 best antenna for portable?

[@COASTALWAVESWIRES]

From what I’ve learned the coil antenna when tuned properly is a resonant antenna and will have less loss than an antenna with a transformer. For the small shorter size it’s a great antenna but probably doesn’t perform as good as the long vertical half wave antenna.

[@NickkoG]

@@COASTALWAVESWIRES Thanks for your answer. I thought the loading coil was only there to adjust the impedance and therefore did not do more than just a transformer.

[@z8ty]

Hi Walt - Based on your initial review, I purchased a HF 360 from Sigma. The tip of the whip is at 24'. I do not have any radials and it works okay. FT8 contact in Mexico was about as far as I've gotten. SSB as far as California, but mostly closer to QTH. On average I see that 1000 - 1500 miles. I am assuming the metal roof/flashing whatever it at your home/condo was acting as a ground plane in your first video. Unfortunately I have no way to run radials; perhaps I could add some rigid radials, but I would need to figure out if that would be helpful and if so, what length and how many. Your audio was not the best ever... I will have to watch again with headphones on. Thanks for the info. Hope the trip goes well.

[@COASTALWAVESWIRES]

Thanks for watching, sorry for the audio, I'm having some issues with that as I'm travelling. All the best and 73!

[@radiotests]

Your radials should be 1\4 wave to desired frequency of the antenna. 3 or 4 it's great. If you want it to be more directional have them form a V open to the long path for DX. 4' above ground is good but a full wave or half wave is perfect.

[@Mr__Anon-E-Mouse]

Even with the echo it's a good video

How about a one month trail of QSO's as a Reply on your video description of others to see what you did I am sure you have a log?

[@COASTALWAVESWIRES]

I'm not trying to make a pitch or sell for the antenna. As I stated in the video there are numerous contacts with this antenna in my videos. Going through my log and pulling out the contacts with this antenna throughout all my other contacts would take me some time and right now I just don't have that time. Sorry.

[@giulianoggg2035]

I bought one today I will son install it, did you ground the base pole or mast?

[@COASTALWAVESWIRES]

No mine is on a rail on a fire escape but yes you should ground the base pole / mast.

Reminds me of a silver rod cb antenna

[@redjohn20001]

On 10m its around d a half wave. If it was fed with a 49:1 unun?
