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.
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!
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.
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. 🙋
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.

@@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.

@@yqtszhj fantastic, well done. 73's
Simple is best Brian! Hopefully this will encourage others to try...
@@theradiorover yes, just did 5w to France, so iam happy. 73

Superb Brian. Working well mate 👍 73 Nigel G4BSW

@@aerofart you are perfectly right, a knot could be used.
