Wire Antenna

I finally got my last wire antenna trimmed out and up.

It is a half wave on 80 and fed at about 1/3 way from one end. One leg is 45 feet the other is 90 feet. The thing is similar to a Windom. Covers multiple bands without a tuner. Drive point impedance is around 300 ohms. I have a 4:1 balun at the feedpoint and run 50 ohm coax from there.

SWR around 1.5:1 on 80, 40, 20, 17, 15, 12, and 10.

SWR 3:1 on 75 and 3:1 0n 30.

I can put a 100pf capacitor in series with the 90 foot leg and that is supposed to bring the SWR on 75 to 1:1 without effecting the other bands. The only band that will not be covered is 30 meters.

Other than being able to use one wire on multiple bands without a tuner there is nothing special about the antenna. Just a 1/2 wave on 80 meters. The radiation pattern gets a little complicated on the higher bands. Multiple lobes especially on 10.

Going to hook this antenna to the Yeasu amp and Omni. With the 950 and 922 going to the antenna switch selecting the 75 meter dipole, beam, and inverted-L.
