I live in Florida 10 miles from what is considered the centered of the place
in North America where the most lighting occurs. I've had a 4 elem Steppir
up for 4 plus years with no problems. I also follow the Steppir e-mail list
and while I've heard of a few control boxes being damaged by lighting I
don't recall hearing of motors being damaged by lighting. I think the
concern of lighting damage to the motors IN THE AIR is much over rated.

I personally would have a stepper but didn't want to WAIT the time it took
for
them to get it to me. I live in high lightning area and didn't want anything
electrical mechanical in the air. (motors)

Subject: [TowerTalk] LP v SteppIR
Gentlemen,
I wonder what the attraction of the LP is when one can use a SteppIR.
Am I wrong to believe that the Fwd gain and FB are better for a Yagi of the
same number of elements tuned to the frequency of interest than an LP? Is
it not the case that LP antennas have a lot of metal and hence wind loading
for what they achieve? Wind loading is as important to me as gain and
directivity. It is a big balancing act. Granted the SteppIR has a good
bit of electronics but in my experience they seem to be reliable. Perhaps
the SteppIR is more expensive for the same performance but Aluminum is
pretty dear.
I am not trying to start a 'barney' but these are just my thoughts and
it may be that some one can correct me. I believe that SteppIR has changed
the entire technology and past equations.

Subject: Re: [TowerTalk] Single Tower, All Band Solution ?
You need to take a look at the Tennadyne T-8 log periodic. I have 8 towers
and have run most every antenna design at one time or another and it is one
of my favorites. 5 bands, cw to ssb (try that with a trapped antenna),
instant band switching, no matching network, light and really low cost.
