Subject: [TowerTalk] Vertical top-loading questions
A quick question:
I have an elevated 80M 4-square made of Rohn 25. There
is 15' of tower, then an insulator, then 50' of tower,
then a 20' whip made of aluminum tubing. Every winter
one or more of the whips break off (even using triple
wall tubing). This year 3 broke off. I have to do
something:
1) Extend each vertical with 1 or 2 more sections of
tower. This costs $. I have the tower, but the
Phillstran, and Grips X 4 towers adds up quick.
2) Take the whips off and top load each tower with a
piece of wire strung to the top of another tower.
Thus I would have 4 inverted-L's, but the top
horizontal portion would be exactly horizontal.
Would #2 alter the gain or pattern much? I think it
would decrease the bandwith, but this antenna is used
mainly on CW.
Thanks for any opinions.
Bill, WB0O in North Dakota
