[Elecraft] Six-meter Antenna Tuner

[Geoffrey Mackenzie-Kennedy]

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
