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.
