Doublet Antenna question
Currently I have a coax fed trapped 75/40M dipole up between two trees. The spacing of the trees (a bit over 110 feet) allows this antenna with no extra length allowed, except for minimal support line and insulator length. I plan on replacing this dipole with 450 ohm ladder line feed doublet so I can operate on more than just 75/40M, however a full 1/4 wave length for 75 would be too long to fit between these trees. My QUESTION(s): How effective would a balanced fed dipole of about 100 feet length be on 75M ? Should it tune OK with a tuner such as the new MFJ balanced tuner? Or, if I were to put either the old 40M traps, or wind coils for the new dipole to shorten 75M resonance, would it then tune OK on all bands from 75M down with balanced feed? Ed K7AAT |
