Well I give up I have no room for an 80m antenna my plot just isn't big enough spent 2 days trying to fit in an inverted L W3DZZ so if anyone has any ideas how to fit 20m of antenna into a 13m x 5m garden I'm all ears. Before anyone suggests going over the roof.....it's a 3 storey house and it's flippin high......ask Cambell 😂 ... See MoreSee Less
Get a Titanex 1/4 wave..... apart from the crap construction, it works great
Sell the house and buy a bungalow.
Have you considered one or more zigs or zags (not sure of the difference😄) in order to just get the length out there. Maybe let the far end dangle a bit? More than likely a tuner will be needed but that may have been the case anyway. Lobe pattern will probably be crap but might be good enough to get a signal out.
Go over the roof, tennis ball with string on it over first, then pull over the W3DZZ, simples! 😄👍
Here’s mine, you can just see the trap above that house. Mine goes over and down the gutter at the front, the other trap sitting on the roof tiles, works fine for me 👍
Capacitive loading. STL. Helical, like RadCom Antennas October 2017 (can send you a scan if you want) or something from Stealth Antennas
Okay... Will need to separate the pages from the pdf (I scanned all the antenna articles 😉
I did some testing on my vertical. It didn't pass the test, top 13m fell off
A 49:1 wound on the 140-43 core with 3 Turns : 21 Turns and a 100pf cap across the primary. Pretty standard stuff. To test it, I strung up a half wave wire for 20m in the flat (indoors!). First try at 15 Watts - UA9M at about 2850 miles, 599 both ways. I'll take that. Time to box it up.
Sounds like a good ‘un!
A nice we story and design for the newsletter Ronan.... you know I am always looking for articles
I used 2 these polos for a 4:1 balun at the centre of a Windom and another as a choke on the coax feed.
I didn't and couldnt justify spending big money on a prebuilt antenna.
