How about hanging an inverted V dipole from the Hazer for now. Mine is
35 feet in the air and has 3 sets of wire, 80, 40, and 20 which I
adjusted for a reasonable SWR on each band by adjusting 80 first, 40 and
then 20. The RG-8 coax feed has a 8 turn coil on a gallon plastic jug
at the center of the dipoles. The SWR will never be 1:1 so a tuner is
still needed. I have run run FULL power to the Drake MN2000 tuner and
antenna with out any problems.
The MFJ rotapole sounds like it would be a bit stressed on 40 and 80
with max AM power.
Also it would have to be 120 feet in the air to see any real benefit of
rotation on 80.
