Ham Radio - Can an antenna work while laying on the ground?

[@loughkb]

Great comments guys, lot's of good information here. To the guy who commented about "kilowatt". I didn't get that you were talking about phonetics. Ignore my reply. I realize there are a few people out there that adhere precisely to the official phonetics. I mostly do. But I'm not going to get all worked up about someone deviating slightly, or more, from them. As long as the intended letter is communicated via a recognized word, the job has been done and communication succeeded. Isn't that what really matters after all?

[@UnkleJustin]

I am an NCS for Maritime Mobile Service Net. We ask folks to use the IARU phonetics. Ships and general check ins ALWAYS give me goofy phonetics. But when the Coast Guard (and recently the USAF and Canadian Forces) come onto 14.300, the folks always go back to standard. It's proper, respectful, and easy to do when an authoritarian 20 something yr old military voice comes on air 😎

Is "Kilowatt" supposed to be decoded as KW or K? It's a tad ambiguous. Why not just "Kilo"?

[@johnk8091]

Interesting Kevin. Soon after I first got licensed in the early to mid 1980's, my HF beam antenna was down for repairs. So for giggles, I threw a pile of wire out the shack window onto the ground outside. It was raining at the time and so I didn't extend the wire along the ground - I just left it in a heap below the window. I got on 20 meters with an ATU and to my surprise heard the band full of west coast stations on the long path from my location in South Africa. I put out a call to a station in California using 100 watts, and he immediately came back with a 58. That is the power of being near the top of the sunspot cycle - Africa to California with 100 watts, and a heap of wire lying on the ground as an antenna 😂

[@aaronedw77]

I have had amazing results with loop on ground antennas for RX 160M-20M, KK5JY has a great write up on how they work. A conventional antenna simply placed on the ground will perform very poorly as demonstrated. But a Loop-On-Ground Receiving antenna will have low take off angle, low noise, a bidirectional pattern, with 2 LOG's (1 with a delay line) you can get ~20 dB front to back in my experience! And at only 15' x 15' the loops only need 60 ft of wire, even for 160M! A very long time ago most hams used separate gear for Tx and Rx so it was not such a big deal to use two separate antennas, but since the integrated tranceiver became the universal standard the idea of dedicated Rx and Tx antennas has lost popularity. A high Q mag loop for Tx, and a broad band LOG would give you a very capable setup, with easy deployment. 73. AD0WQ

[@paulschmolke188]

On ground is OK for receiving but as a transmitting antenna you’d just be warming some dirt. I’m currently using a random length wire and counterpoise as a receive antenna. It’s temporary but OK for AM DXing. I’ll be building the LOG and probably adding a preamp at the antenna. Glad you tried it out and showed how you did it. Thanks.

[@UnkleJustin]

You have proven that messing with tennas (ahem, performing antenna engineering experiments) is still fun!! Especially in beautiful locations. Thanks for video de Tim KB2RMC

[@JohnTarbox]

When evaluating a receiving antenna signal to noise ratio is more important than signal strength. Simply comparing S meter readings was not really a fair test.

[@41divad]

In the late 70s I listened to shortwave radio while underwater in the Philppine Sea. Would hook up to the floating antenna and listen to dramas from Australia northern service. Great reception

[@TheStevenhull]

Hi Kevin, I can answer about ELF, I use it everyday to locate buried utility lines with. We use an 8Khz sine wave at 1-3 watts and can get a few miles out of it. Switching to 33Khz drops the signal drastically for distance. Ground soil conditions has tons to do with being able to locate the lines. When you get a chance look at Clam Lake, Wisconsin and the antennas used to communicate with submarines, very intresting.

[@Paul-gz5dp]

I have seen the charts that have been made in the past for the depth of penetration in earth and into sea water versus frequency and baud rate, and the deeper the lower the frequency and lower the data date for the signal to get through. There are not many of those high power ELF transmitters left. Many have been closed down and the land sold, along with air bases and other military property in various areas. It leads one to wonder where the future good engineers and operators will come from, as people can take classes on most anything, but that does not teach them much in the practical applications, only theory and very little hands on and experimenting. Once someone knows things well they can work with most anything, but those trained on just one piece of equipment do not do well when things change. I have seen this time and time again, as I can easily fix and redesign things even without any schematics that others who have no experience in the designing and building of the same equipment are lost with simple repairs. I know that many today rely on simulation software, but that only works when one has a computer on hand, and does not help when the computer does not work or something unexpected is observed. As with most things they just put in a fudge factor and push on not knowing fully what they are doing or knowing what to fully expect. It takes experimenting and experience with many things to find out the differences between ideal and the real world. As the real world is more complex than any of the equations that one will learn even at a Masters or Doctorate level. It is this experimental experience that people get with listening and designing equipment, and being a Ham that is the only way to understand how the future will work and how to make it happen, as for it's existence in the first place. Also in the 1930's and so forth it was operators that built their own equipment, and I got my interest in electronics from Electronics World, Radio Electronics, Popular Electronics, ARRL radio books from the 40's and later. Just have avoided even considering becoming a ham because I'm so bad at learning code. Easier for me to figure out how to design and build a box to listen and translate than listen and write it down, and that is because of my learning disabilities that make communications difficult for me since a very young child. Things hard for most are easy to me, and things that are easy to me are difficult for many others.

[@jerrykrautenstaben6584]

Great vid. One comment. If you notice, at the 6 min mark in your vid it shows the noise level on your scope with both the in air antenna and the on ground ant. The on ground antenna has much less noise compared to the in air antenna. For transmitting, the in air antenna is almost always be better, but as a receive antenna, the on ground antenna can help dig those signals that are buried in the noise out. Sig strength will be less, but sig to noise level will be better. This is the idea behind the beverage on ground (BOG) antenna. Sometimes having both and a switch between the two helps with pulling out those weak stations. Thanks.

[@fitybux4664]

It could have been better at receive because it was closer matched to the wavelength.

[@grs6262]

ground mounted antennas are usually aimed at obtaining a lower signal strength to noise ratio--the signal strength drop off is usually less than the noise drop off, making reception much better--if one tries to transmit thru a ground mounted antenna, usually the effort comes to grief-- i have a 28 foot diameter loop that many times is my best antenna for reception on 160m and even occasionally on 80m--unfortunately i can't get that loop directly on the ground at my present location--if i could, i suspect my S/N ratio might improve even more---but i wouldn't dream of trying to transmit thru it--

[@BMCTackle]

I live in an HOA, so experimentaton is imperative. I have a temporary 40 meter dipole set up in the yard. It is about 2.5 feet off the ground, definitely below 3 feet. The legs on the dipole are 30.1 feet per side, that is what it took to get an SWR of 1.2 or better on the general frequency range of 7.178 to 7.300 MHz. The antenna has been working great, didn't think it would get past Wyoming, Arizona, Colorado, & Nevada, but it has, and not bad, LOL. I am in NE Utah and have had QSOs all the way to the east coast, signals of 2/1 to 4/4 , which is way better than the total ZERO I expected. Given the actual band conditions (not the good fair poor ratings found on the daily Solar Terrestial Data forecast) this antenna has done pretty good. I go on the OMISS 40 meter net in the evenings, and this is where I have been testing it. This is a temporary setup, I hope to put it up to 35 feet later this week, waiting on a friend to bring the ladder we need to get up on the roof. I have been using this setup for the past 4 weeks and I am impressed with its performance. I would love to see what it will do on a day where the actual band conditions are good, but I am more anxious to get the antenna up and working under normal operating conditions. Given the HOA thing, I am happy that it works where it is now, not optimum, but it works, it is an alternative should the roof mount become an issue. My elevation here is circa 6900 feet. The soil is conducive to plant growth, flowers, berries, apples, & vegetables, the soil retains moisture, but by 1 PM it is dry, and I set the sprinklers to go off at that time so the Kentucky Blue Grass stays green. When we dig here, it is mostly large rocks going down, the 8 FT copper ground rod became an angled one, no way to it drive straight down here. We are in the Rocky Mountains, LOL! WW7GBA Louis

Hello Kevin. I'm in the process of making the LoG (loop on the ground) antenna. It is two 15'x15' square loops in phase to produce a sharper bidirectional pattern. This is a receive antenna only. Each loop will have a 6.25:1 transformer at the feed point and fed with 75 ohm coax. I'll be able to compare the snr with my 80m full wave horizontal delta loop and 3/4 wave inverted L which are 50' off the ground. I'll let you know the results. 73 Scott - kl4nu

Kevin...in this video when you were tuned to 3.923.5 that was me calling the net. The rig I usually use it my IC-7300 driving a Heathkit SB-220 running about 800 watts output to a 160 meter doublet. I was surprised how strong my sig was with your antenna laying on the ground. I have done the same experiment you have done with a G5RV and found the same as you did....it worked but not anywhere as good as when it is strung up in the trees. 73 WB7S

[@tangobayus]

Remember that an antenna on the ground is probably a NVIS (near vertical) antenna, so it will be best on 40 meters in the day and 80 meters at night.

[@porkyfedwell]

I use a groundwire antenna that is under my grass in SW Ohio, for nighttime listening to hams (cw, ssb) while I drift off to sleep. No worries about lightning since it's in the ground and only a 28 gauge enameled wire which won't carry much current. I get ham activity coast to coast with no problem. The grasswire works great for me!

[@loughkb]

Yep, but one thing. You're not immune to lightning. Any nearby strike of a building or tree will generate a huge electrical pulse in the wire, even on the ground.

[@JohnCorby]

I have QSOd on ground antennas. The wire must be at least one wavelength long and radiates off the end of the wire. The longer the wire, the lower the take off angle. Ground antennas are lossy but are also directional. If you need a stealth antenna this is a good compromise solution. Check out K3MT's "grasswire" experiments in Bermuda.

[@KjartanAndersen]

Wether or not an antenna will work lying on the ground will depend on the ground. I have used a special Harris antenna designed for desert and that works fine as long as you operate in a desert as I did in Afghanistan. The same antenna does not work back home. Not even close. But funny enough it springs to life again when put on top of deep snow. We typically get 4-5 meters of snow during winter. To many think of ground as the ground we stand on, but antennas doesn't always agree. Normally it will be correct, but try operating in desert where water is way down in the ground (water surface or water table, I don't know what you call it in english) and the ground it self isn't very conductive. One of the reasons we discovered something was of in Afghanistan was that low hanging dipoles didn't give us NVIS. Not until we placed a wire as a reflector on the ground below the dipole. After a while we got hold of this specially designed Harris antenna which gave both decent comms, but also some covert antenna site.

[@BubbaWarbucks]

BOGs (Beverage On the Ground) are a real thing. Actual sensitivity isn't important, because you're looking for low noise and directivity, and make up for the lack of sensitivity with a preamp, and it's a receive only system.

[@mm3nrx]

One time I was doing some repairs to my antenna system and had to lay my beam on the actual roof, I live in an apartment so its hard for me to drop all the antennas, and I was amazed that i was still working DX even tho the antenna was pointing approx 40 degs into the sky due to the slope of my roof :D. I know not technically on the ground but it was flat on my roof...

[@paulsnelgrove1517]

It will depend on the freq. VLF , lower frequencies prefer ground transmission. As you go higher it will fail.

[@de_w8tam]

I messed around with a 'grasswire' antenna, and came much to the same conclusion you did here in Michigan. I recently ordered an interesting noise canceling kit which uses a 'noise antenna' for picking up RF interference to inject 180 degrees out of phase into your receive signal. I wonder how a ground wire would work for that purpose. 73 de w8tam

[@artdodd815]

We did the same experiment on field day about 6 years ago. We made QSO’s but it wasn’t stellar. Art. K2ADC

[@tlebryk]

What was the length of the end fed antenna on the ground? What was the difference in signal to noise ratios between the end fed on ground vs the vertical, especially as you came down in frequency? Did you put an RF choke at the receive end of the antenna (a loop might need one at the antenna feed point as well to keep it from being grounded)? What is the ground conductivity rating at the test site (higher is better for lower angled reception)? Did you try the wire as a loop on the ground with a 9:1 balun (loops don't need a ground or counterpoise)? Did you exceed 1/2 wavelength of the end fed on ground in your tests (loops can handle up to one wavelength before reception pattern goes bonkers)? Did you know that you may have just been warming up the earthworms trying to transmit into the ground (a loop can make a useful Receive-only antenna if one has space restrictions)? Did you have a preamp turned on which may have just amplified the ambient noise? Did you see this web page ( kk5jy.net/LoG/ )? Did you see these experiments ( forums.radioreference.com/threads/160-20m-log-loop-on-ground.370110/ )? Or this experiment with 40 feet of looped wire, amplified ( kzbin.info/www/bejne/aIrLfGODq8lobtk )?

[@fitybux4664]

If you used a more insulated (from the ground) cord, I'm wondering if it would perform better. Like maybe a long extension cord. (It would have a thicker rubber sheath. Or, it could just be that the horizontal polarization is cutting down your signal.

[@davidsradioroom9678]

Nice to see an experiment "out of the box".

[@johnpawlicki1184]

Maybe you could compare the light bulb to the ground antenna. ;-) We used to employ a 40W appliance light bulb as a dummy load when tuning up some tube transmitters. I think,not always but generally, getting the wire off of the ground is better. Good video. 73.

[@DonDegidio]

Hi Kevin, Think I watched some of those videos you mentioned. I might have tried an on ground receiving antenna the BOG, but had my doubts about it's effectiveness for transmitting. Appears you answered that question. Did you participate in the CQ 160m SSB contest this weekend? 73 WB3BJU

Research the ELPA antenna. There are several papers written and the military had one in production. I have one and use it in other configurations.

[@loughkb]

I've seen that before. Raised 1 to 3 feet off the ground so the ground acts like a reflector. It's an NVIS antenna for near vertical radiation and a local area of coverage. 100mi or so.

[@Paul-gz5dp]

Would that be found on Archive.org?

[@Paul-gz5dp]

The problems I see on the ground is that it is high capacitance to the ground, even though the ground is dry. That being said it will change the effective length of the very least, and that is not accounting for the amount of signal that is absorbed by the ground. There is only one practical use that I could see and that is spacing at a set distance from the ground and tuning for EME or other such communications where the intent is to eliminate one or more signals at the same frequency that are from the horizontal direction. Also when close to the ground I would probably look at that as more of a waveguide than antenna as it would be tuned with the ground as part of the propagation. Also if buried in the ground it would mostly pickup changes in the magnetic field of the earth, power lines and other such very very low frequencies. I know this from experimenting as a kid, before I understood that an antenna is a tuned circuit unto itself.

[@scottrand7626]

Hi ... Did you measure the naked (no tuner) SWR?.... Have played with these critters a bit. Ussaly see the length shrink 20 to 30%. Your right...it all depends on what kind a ground you lay it on... And as best I could tell... it turns a other wise good antenna into a cloud warmer.... signal strenrh will be down 20 dB...(suggest a switchable attenuator)... noise even more... but how would you be able to tell ...with no noise... to be found in radio paridise!!!... Tnx for a great video...73

[@tangobayus]

Could work because your antenna is on a very lossy ground, but having lots of room, you could add "gain" having at least 1 wavelength.

Adding any height is going to improve signal in and out. I'm thinking a wire, strung on the top of a fence, would be better than that ground wire.

Interesting investigation / experiment. Got me thinking, suppose you had a resonant dipole antena, and for some reason you could only get half of it in the air.

[@Paul-gz5dp]

That would most likely work well provided that there is little metal or anything else conductive such as wet roofing near the antenna. You will probably need to adjust for the capacitive effects of the roofing material with an antenna tuner to get a really good signal. Nails are not an issue, just how close the antenna is to the flashing that is used. The farther from the flashing the better, as it will look almost exactly as an open air antenna at the same height. I used to run an antenna under the eve of the roof in a house and it worked great, and I could get signals from nearly all countries in the world in the SW and from 160 to 20 meters. Unlicensed and even though I had a transmitter with an 807 in the final at the time, never thought of putting it on the air.

A buried antenna will have its resonance at about 25-30% of the length of an antenna up in the air due to dielectric effects. The feed impedance will be higher as well. Your antenna was not properly matched. The military has used on ground and buried antennas for years, one application was for backup comms to missile silos. See the text "Antennas in Matter: Fundamentals, Theory and Applications by Owens and Smith" and www.rfcafe.com/references/short-wave-craft/images/buried-antenna-performance-development-small-resonant-buried-antennas-ad-783-274.pdf I use a ground dipole on 472kHz, about 480 feet long ( in free space it would be nearly 2000' long), it has an impedance of about 200 ohms. 73 Warren K2ORS

Moisture content of the ground is surely another variable.

[@robertl.fallin7062]

my thought was a 8 ft ground rod! Maybe insulated wire antenna too.

[@DAVIDGREGORYKERR]

A blade antenna like that used on aircraft might be what your talking about.

Why wouldn't you lay the counterpoise at a right angle?

[@loughkb]

The closest you can get to running it in the opposite direction from the radiator, the better the performance. A 90 degree angle would be the limit before you start to fold it back on the radiator and lose performance.

[@ri3cjoh]

@@loughkb Okay, cool.

[@chrisscott1547]

Simple summary: Yes, but not well.

How about trying going to the beach and putting your ground out into the ocean and land I and 10 on the beach see what it does

[@turbo3089]

Can chicken wire be used as a antenna

[@loughkb]

Sure. I once may a contact using the backstop fence at a baseball diamond. Anything metal can radiate RF, but not very efficiently unless it's a half a wavelength in dimension.

Looked like Quartzsite

[@loughkb]

Same general area. I was about 50 miles south of the spot they do Qfest.

Load the box springs. Hihi

Ground antennas work IN the ground, not ON the ground.

[@Barracuda48082]

Geez,, 1s over noise floor and they still stomp you.. ha.

Several questions....So are you basically homeless now living in a camper? LOL we should call you the Nomad Ham. also I would not think it would be very quiet as all those campers all have 12 volt systems with some solar and all those PWM inverters in the campers causing hash......???? I guess its less than in town in a house with all the crap we have plugged in these days?

[@loughkb]

There is some noise. I can tell when my neighbors have their TV's on. Between the noise, the floor is S0.

[@AlGritzmacher]

It can't possibly work because it's "grounded" ;-) ha ha...
