[Towertalk] hygain 205ca

[Mike & Coreen Smith]

Ed,

Aim the antenna as straight up in the air as you can, reflector resting on
the ground, with the director up in the air. The entire antennas will be
perpendicular to the ground.
Sawhorses are no good for HF (or even 6m) antennas. Ground is much too
close!
