There is no straight conversion for AC/DC to RF use General spec can lead to some insight. Breakdown voltage across the contacts should be above 1.5KV for a safety factor of 2 above a 4:1 VSWR into a

on the 70' tower I'll assume a minimum of a 10' mast exposed at 70.5' 3 or 4 element 20m yagi at 77.5' 2 element short 40m If possible at 35 to 40 ft 3 or 4 element 20m yagi same make as above fixed

You wont get 3dB at best for a 3 element yagi on 20m using a 30' spacing is 2.5dB max. Add in an additional say 20' of cable say rg213 and you will have more loss. say another .25dB. That assumes the

Define interaction. Do you mean that 15' is enough so that the interaction has little impact on the 15m VSWR. Or do you mean that 15 feet is enough to reduce the interaction levels for gain, f/b and
