I have a shortened all-band dipole with two loading coils on each leg.
On 80 and 160 it has a very narrow resonance bandwidth that requires a choice between data (low end) and phone (hi end). I am using a wide-range manual tuner. By changing the length of two segments on each side, I can move the resonant "passband" where I want it on 80 and 160. Using the antenna outside the passband results in unacceptably huge (like 99%) feedline losses -- when the feedline is coax. I suspect that if I shift to ladderline, the losses will just move to my tuner. What would happen if I adjust one leg for resonance on phone and the other for resonance on data? If this would give me 50% of the resonant signal of a balanced antenna, that would be acceptable. Ken KC2JDY Ken (to reply via email remove "zz" from address) |
