As far as I know that unit uses reed relays, and should have no detectable
loss. I think there might be two models of that,

On my Beverage antennas (which are low gain) the accumulation of AM BC
signals, SW BC signals, and so on at night is enough to light the filament

You are correct. In my case, I am using a ferrite loop on 160 and a short

are a vertical on 160, and full size dipoles and a beam on the other bands,

Here is a very major problem people with slopers should watch for. The
sloper uses the tower as the counterpoise, and the tower structure has the
same current at the connection point as flows into the sloper wire we call
the antenna! If we have three amps of RF into the sloper, the tower is

I can't do that here Vic because on most of my antennas the

I.C.E. makes a very cost effective unit that gets the job done very

Jorge,
The clicking you hear is the COR (carrier operated relay) on the RX ANT
activating to protect the K3 receiver.
Your 40 mtr Yagi is picking up much more of your TX signal than the
Beverage.
You should take steps to reduce the amount of TX signal picked up by the
RX ant.
