[TowerTalk] LP v SteppIR

[Doug Turnbull]

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.   

                   73 Doug EI2CN

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.
