I am running a 100 ft bowtie antenna ok with link coupled transmatch, fed
with 450 ohm twin lead and it tunes 75 thru 10 meters
Each side of center feedpoint has a pair of 50 ft wires, that are connected
at the ends with a piece of 6 ft wire.

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?
