Re: End Fed Wire (Was NorCal Doublet)

You will find that 124.5 foot wire works on ALL HF bands
- if it is anything like the one used by WB4DBO.
(As seen on his QRZ page.)
Mine is 100 feet long with the 9:1 transformer, but also works excellently! I think UNUN is a bit of a misnomer. It;s just a transformer and everything happens to be relatively unbalanced - coax on one side and a single wire on the other side! Yup, it had me confused too!
It's the best all around antenna I ever used in 48 years of hamming. What got my attention was the excellent signal I ALWAYS heard from WB4DBO on it!

Just to add my $0.02 worth.
I needed a wire to operate 80m so I went with a 124' 6" length fed via a 9:1 unun, works a treat on 80, loads on 160 as well, (as well as all the other bands up to 6m). Starts off at around 10' agl (unun is in the attic) with the far end at around 30'. The unun is at one end of the house, the shack at the other so coax from ASTU to unun is around 80'. Gets ny 5 watts from SE Kansas to NJ. Works for me. My other "go to" antennas are a 66' wire +33' counterpoise and a W3EDP fed with a 4:1 BalUn.
Just a few more ideas to keep the pot boiling.
