[TowerTalk] HyGain 155CA dampening rope

[David Aslin G3WGN]

Thanks to all for the wisdom, both on and off-reflector.
Clearly the rope should be used with this antenna, as insurance against the PITA of taking it down to fix a broken element, if for no other reason.  And I learned too that the vibrations that lead to element failure can be just as easily caused by a low velocity wind as a high one - so my exposed site is not the real reason to use the rope.
I also got some very helpful practical suggestions on end cap installation and torque balancing the antenna.
I love this reflector! I'm good to go now with best practice for this antenna.  Thanks again guys!

Whenever I used Poly Rope in the
elements, I would use Epoxy. First
at the far end, then tension the rope
with a weigh and epoxy the near end.

Never had a failure.

Also, did the same on verticals. Never
needed Guy Ropes on them.
