[TowerTalk] High VSWR

[Wayne Kline]

Peter,

WOW  great looking installation.  RGR on working alone. I have had help  at times but most of the time it’s just me and the station was designed for that.



As for weight compensation  it first came into play with me was  building the famous  W2PV-4 antenna  they were side mounted and I ran into trouble with the ganged element  at the driven/reflector and 1st  drive element all grouped  close together.   So I used  aluminum angle  stacked and  banded to the end boom to achieve a balance at the mounting  point.

Yes, that is the only reason for me to counter weight the boom, to have it straight when I pull up or lower the antennas.
I do all my antenna work alone with the help of an electrical winch and need the booms always straight for mounting them.

I understand the objectives and mechanics of wind torque balancing of a
beam. Leeson explains how to do this with round elements so it works at
all wind angles.  (Physical Design of Yagi Antennas, chapter 6)

However, I don't understand why a counter-weight balanced beam is  a
benefit other than when tramming the beam and for on the tower work.
