Ok Folks, Thanks for the reality check. I didn't particularly care
for the idea I was purposeing but was hoping for at least one "yeah
you'll be ok if you just do....." Instead I was inundated, quite
quickly I might add, with "DONT BE STUPID!!!". As anxious as I am to
get a decent antenna in the air (16 years of wires) I can wait until I
can do it right. At least I will have the antenna. Just need to find
a tower to put it on. And I want it to fly before the 06-07
contesting season starts. I really want to start doing more than just
working the loud ones!
In the "just so you don't think I am a complete idiot" catagory; The
20' of pole is 2x10' sections of 2"id thick walled steel pipe. The 6'
peice is 1.5" steel. I know the HD73 is a smallish rotor but by
reading the specs I thought I would be fine. It specs out at 10 sqft
windload and the KT34A specs at 6 sqft. The height above the rotor
had me concerned as well, for good reason I see. Power lines and
other structures are 70' away.
Thanks and vy 73,
