Hank,
My suggestion is use a classic link coupled balanced "antenna tuner". If you
cannot find one to buy the cost of building one for 6m at the 100w power
level should not be very high. The third edition of 'The Radio Amateur's VHF
Manual' (ARRL) contains a couple of examples for use at other power levels,
please let me know off-list if you would like to see these.
An eighty metre dipole should work well on 6m in certain directions, after
all it is a centre fed 7 wavelength (approx) longwire at 6m. The horizontal
pattern should have 4 narrow major lobes, 10 narrow secondary lobes and deep
nulls off the ends.
73,
Geoff

Since it is part of the K3 package, I would like to try six meters. My
one and only antenna is an eighty-meter dipole 46 feet above ground fed
with poly ladder-line. I'm looking for suggestions for a 100-watt coupler
that will tune a balanced-feedline antenna at 50 MHz. I do not have the
K3 ATU and am looking for something considerably less expensive.
All ideas are welcome, but please don't suggest some other antenna. My
antenna is what it is. Because of town esthetics and very harsh winter
weather I'm lucky to have the antenna at all.
