Other than the three Magic T's, what other specific mods have you made to your
Adding a T50-2 toroidal inductor and a BNC connector at the 50 ohm tap makes a
quick job of adjusting resonance to exactly 1840 kHz.
Much more work is planned later this year, building switchable 8-circles for
160 and 80 meters.
Using one inch rebar for the base makes that job a snap, especially in my case
where I must completely remove the antenna from my borrowed field every year
and reinstall it in October. The rebar can be easily removed with a sledge
I discovered that I couldn't unzip my 16 AWG speaker wire when its cold, I was
breaking wires! No problem at all unzipping it at room temperature.
Tks for all of your help!
