- Has anyone on this reflector been able to detune a grounded tower using one or two drop wires instead of the Usual three. I presently use a gamma rod to shunt-feed my 70ft grounded tapered tower maki

- Hi Gary. Although I have not had the opportunity to implement a tower detuning, I have given it a bit of thought and wonder if this idea would work. You say you already have a Gamma rod which makes m

- Hi Gary, With the tower only 70 ft high, you should get enough detuning simply by disconnecting the coax from the shunt feed with a relay, when on Rx. 73, Greg, ZL3IX ________________________________

- _____ I have a nearly identical situation to Gary -- 72' tapered self-supporter, but currently there are no antennas installed, and very little re-radiation. However, this tower will approach resona

- You say you already have a Gamma rod which makes me think you also have a simple series matching capacitor to your feedline. I would think that relay contacts in that drop line could select either yo
