ZL3XDJ, 20M Elevated vertical VS 3 ele parasitic vertical.
มุมมอง 3K21 วันที่ผ่านมา
which is better, my old 3 ele parasitic vertical antenna with 300 radials, or my new 1 ele elevated antenna, with only 4 radials. What a surprise i got testing these ants, and some results not found here, which are not in the handbook. Thanks to the station master/xyl/ wife , for her encouragement for more ants equals more enjoyment.

Simple is best Brian! Hopefully this will encourage others to try...
@@theradiorover yes, just did 5w to France, so iam happy. 73
Why not just tie a knot in the radials and the radiating element wire coming out of the box? It would then require only one hole per wire to be drilled and would provide the benefits of simplified routing and a box that would be easier to make weatherproof. The only thing I can think could be a problem with this method is the introduction of a small, parasitic induction created by the loop in the knotted wire, but at HF frequencies and with such a small knot, I can’t imagine that any such induction would be consequential.
@@aerofart you are perfectly right, a knot could be used.
Thanks from Adelaide
Great video. The low angle take off of a ground plane antenna will often compete with a Yagi beam. I worked Australia from here in Florida with only five watts SSB using a simple ground plane hung from a fifty foot pine tree. I have also worked hundreds of stations from all over the world using one hundred watts. It is the very low takeoff angle from a ground plane that makes the difference with DX. Going one step up, phase two ground plane antennas with a switched piece of coax to be able to select a direction and add some gain.All the very best from Florida, USA. I will look for you on the bands, Dave, N2SN.
Great video. I have made a similar vertical antenna made from a 24 foot painter’s extension pole that is resonant on 20m. The first section is fiberglass and about 2.5 m long. The 2 extension sections are aluminum and combined are about 15.5 feet. I use four 5 meter radials that slope from 6 foot to ground level. SWR is good and I have made contacts to all Europe and as far south as southern Chile from here in the SE USA. Also it is a very quiet antenna. I can also feed it with a 64:1 Unun and use it for 15 and 10 meters successfully. Thanks for the excellent video. KQ4VGE.
@@yqtszhj fantastic, well done. 73's
Superb Brian. Working well mate 👍 73 Nigel G4BSW
Made something similar for field day with a fiberglass fishing pole. A GP for 20mtrs with 4 radials at 45 degrees angle that also served to keep the rod upright. Worked great!
@@RogierYou well done, I hope you got some nice contacts. 73 brian.
Hi Brian, well done. That should encourage many to give this simple antenna to try. 73 Peter.
@@watersstanton cheers, 17m good this evening, despite the gales with rain and sleet.
Fantastic antenna and signal Brian! 20 m was very noisy on Friday (think geomagnetic storm going on), and I was running just 5 W as usual, and into an Ampro 20 whip on a magmount while parked up at Devils Dyke, but great QSO again. Thank you so much. 73 es 77 M3KXZ
Hi Brian, In 1955 as a child in Sumner 100 yards from the beach with a crystal set with a beadspring aerial aerial and headphones under the pillow so Mum thought I was asleep, I listened to many a nightime US crime serials from 3ZB. But, please tell me if you think your signals to the UK travel the south longpath or the north route. The reason I ask is that many years ago I read that Invercargal was a great listening area for WW2 German U boat Atlantic transmissions. Your aerials are very interesting. Sure, with a mobile phone or 500 W on a beam - well that's no challenge - but QRP on a thoughtful wire and/radials is a learning and pioneering endeavour. Less is more. 🙋
My sig from here in the evening will be long path.
Hi brian just watched that one well the 17mtr vertical certainly doing the biz too as for paul i can hear him on every band 20 over usually got a dx ers hot-spot were he is and of course his 4 ele doing the biz .73 pal maybe we can do it 17 too😉
@@johnmarron1944 yes 17m one day, but it's open a little later here, you might be at work. Next time I catch on 20m we can go to 17m straight away. 73.
Another great watch video brian keep them coming..i am going to put a vertical up now to compare against the hexbeam next time we meet up i will do a test may be a few weeks before i get round to it .all the best . Ps your old town still looks the same ( tom jones ) comes to mind lol
Grand job - thank you Brian. Like others I came to you via Peter, G3OJV. I used MMANA-GAL to model the simple quarter-wave vertical with two elevated quarter-wave radials. To be clear, I use modelling for coarse steering and to gain insight. It may be that your recent rainy spell has been your friend. Increasing ground conductivity lowers the angle of maximum radiation (which becomes zero over a conducting plane) and increases gain by up to a few dB (but less than 1 S-point). That noted, I have no explanation for why your simple vertical out-performed your array. Peter gets better results from a horizontal wire at about 7.5 metres up and I can't do any better than share his speculation that something about ZL favours vertically polarised waves. There's just so much not to understand, which is why your cut and try approach takes a lot of beating! 73 Ian G4COL
Morning brian got quite a pleasant surprise when you came back to my cq this morning i was beaming over Europe so you were on the side of my antenna lol its certainly working very well ..ps a couple of years ago i did a lot of experiments with a vertical set up like yours .trying all radials then just one at a time made no difference east south West north pointing individual radial or all of them still got exactly the same hits on reverse beacon tests 😉.73 john m0asn
@@johnmarron1944 always great to hear you john, and your always a great copy. Thanks mate, 73.
Ps ..when I was experimenting with the vertical I tried a reverse beacon with the 4 radials horizontal. I was hitting into all Europe then I altered the angle of the radials more and more in an angle going to the ground the more steep the were the further my signals were heard usa and vks Asia etc so them angles from the radials make a massive difference too plus I put a reflector behind it 😉
Hello Brian , I spoke to a G3 a while back he's qrp 10w cw, all of antennas are vertical and 6.6 ft of the floor including radials. It all they used verticals back in the 1950's when he qualifed, amazing, I also follow Peter and it's all good info. I'M A GW4 live in a dip land wise but experiments with antennas is great fun

Great video, Brian. I use a 5 m vertical telescopic whip on a 1.2 m tripod, and one elevated 5 m radial for POTA. Worked mostly 20m, but tune up to 6m, with my Xiegu X6100. I'm going to do a comparative test with two radials soon. I may take you up on the offer of a sked some day. 73 from Norway, Tom LB8X, mostly portable.
12meter XHD Spiderbeam is showing up today. Think I need to experiment 😎
@@HamRadioN0CKL experiments and comparisons, are the way we move forward. Good luck, 73 zl3xdj
@brianfields4479 Brian have you tested 1/2 wave vs 1/4 wave vertical on 20?
@@HamRadioN0CKL yes I have, in a previous video, about radials or not radials. Half wave did not require radials, just a balun. 73.
Very nicely done Brian! I'm going to be stringing a couple of elevated vertical wires up in one of my trees later on and leaving them. Then to operate all I'll need to do is attach the radials. I need covert here so the wires will be close to the trunk and out of sight! Best wishes, M3KXZ

There were, but not today. But 40m and 20m were open this morning via short path. I did hear you a few days ago, think you were talking to roly , you were a good signal here. 73.
@@brianfields4479yes we couldnt quite make the 2 way .. it would’ve been around mid Sunday morning your time I think.
@@timg5tm941 sounds about right, been hearing uk at odd times recently, things must be picking up. Worked gb2nz this morning on 40m big sigs, and even stronger was g2sz on 20m, and working uk most days long path, bands are really good and getting better. 73
Excellent!
It was invented by W8JK around WW2 and is called a ground plane antenna. W8JK only specified two radials but other people wrongly thought it needed four to provide omni directional coverage. .
Thanks, I'm working on a 15-10 meter ground plane using a photography tripod and telescoping poles top and sides. Two radials provide balance. More than two radials would get unstable in a wind.
Excellent Brian, get one up for 10m too. Roly worked MM0ZBH who local to me on CW yesterday.

Excellent in-depth experiment with lots of interesting data to take away! There is a saying that one elevated radial is worth of 3 ground radials, it seems true in your case! CU on the bands Brian! 73! Linas LY2H

Ism doing the same thing - with a twist. Vertical elements are two 17ft telescopic whips raised about 2.5 meters above ground on studio light tripods Radials are elevated , sloping down, terminatimg 1 meter above ground on plastic tent poles. Two radials on each elements and pointing about 45 degrees apart towards front MMANA saus about 8 db front/back ratio - practical tests not done yet due to band conditions on 14m This setup is really a combo of two of your videos

1-3 S units?!?! WOW. A huge difference! Based on your previous videos, I was very tempted to try the 3 element parasitic. Very glad to see I can simplify, even though “for now” I only operate mobile (but I am over 3/4 towards Mobile DXCC). Maybe I can set up a single element w/radials for a portable setup.

Mate, how.muxh more could you get with a Raised paracitic reflector with radials behind that antenna. Out of interested have you tried coupling your radials between the driven antenna and the paracitic reflector?
@@DarrenBainbridge yes I did have one big radial field, all connected, same on tx, but on rx a bit more noise for some reason.
First DX nearly 40 years ago as a U.S. novice was Rochester, NY to Buenos Aires, Argentina using an elevated ¼-wave with four elevated radials on 10 meters. These antennas can be DX gorillas and cost little to erect.
@@richegan7381 yes ,simple resonant ants can be fantastic . Many seem to think, the more money spent, and more parts to a ant, the better it is going to get real dx. 73 zl3xdj
Thanks for the great presentation and advice. I've been running a 40 to 10 end fed for a while, and after seeing what you've achieved with so little, I've decided to try your suggested approach.
