[TowerTalk] TH-7

[Bill Parry]

I was thinking about the point John made about the drip holes being oriented
down.  I had a TH6 years ago and it was mounted upside down by the tower
guys. Every time it rained, the antenna stopped working. I took a day or two
for the water to evaporate.

Incidentally, I had problems with the balun.  I made the mistake of
transmitting on 40 and fried the balun in no time. Only ashes left in that
little black box. I think I would use a little "beefier" balun. (Hurricane
Allen didn't tear up the antenna at 150 feet, but it did blow the top off
the balun.)

I have a TH-11 which is pretty much a TH-7 on steroids. I have never had any
problems with SWR changes in different weather situations (I live in wet
Seattle, WA). I put it up about 4 years ago and bought it used so it has
some mileage on it. Hopefully all of the trap drip holes are pointing down.
It has been a pretty good antenna with stable performance over time and
weather condx.
