[TowerTalk] Tribander SWR

[Tim Long]

Point the antenna toward the sky with the reflector resting along the
ground.  Make the boom as vertical as you can.  Use a short piece of coax to
get your body out of the antenna pattern.  I've stood on step ladders and
adjusted gamma matches this way.  It is an old trick.  Measurements will be
very close to the 50 ft high position.  Good luck.
73, Tim, W2UI
