Stan - LOVE "just my 2Hz worth" stealing that from you om!
First of all thank you to each one of you who have contributed your thoughts
particularly around the mechanical considerations for suspending the InvL, You
guys are great teachers. Says the guy whose dad was the ME in the family and
raised a son who had a tough time with math so he went into sales... I am
grateful for the grace you guys have for those of us to whom engineering does
NOT come naturally..
FWIW, my weapon of choice for the past several years for launching lines over
very high tree limbs has been the PVC cannon discussed in QST some number of
years ago. My only changes to the design have been (1) to fill the projectile
(also made from PVC) with lead fishing weights, initially so it could pull the
monofilament I was using as a tag line back down the other side of the Douglas
Firs which present a lot of friction.
I learned that (2), braided fishing line is lighter, tangles far less ( limp by
nature), weighs much less and therefor can be shot much higher, presents less
friction over the branch (almost guaranteeing you can get it to drop back to
earth) and is much stronger as a tag line for pulling the heavier rope or
paracord etc back over the branch ( that you ultimately use for suspending the
antenna).
The PVC cannon is very accurate and I often get compliments from people about
being able to choose the branch and put it exactly where I want it. Its' a
great tool. I can comfortably shoot the projectile over 125' with approximately
90PSI in the cannon
Hope this helps someone..
73,
