Benefits of Son of Mod Bob

There are several things that will be big benefits from Son of Mod Bob: I will remove the center element which is way to close to my 40M vertical array. This will eliminate the distorted 40M pattern I will no longer turn on the Trane HVAC when I transmit at full power I get three antennas in one, a half square on 40, Inverted…

I’m just waiting on…
