Buddy, Everything you say seems pretty sensible to me. Thunderstorms are
not muck of a problem in EI land but I wonder if Florida operators have much
trouble with SteppIR. You can always retract all the elements when not using
the SteppIR. One does wonder how the SteppIR will hold up after ten years.
Thank you for your insights.

Doug & others,
I am going to put up a new antenna this spring, and my choices came down to
either a LP, such as the T-10, or a 3-element SteppIR.
I decided on the T-10 for several reasons. The main reason being I don't
desire moving parts, little wires and motors at 75 feet. We get plenty of
lightning during the summer here so it would only be a matter of time before
something happened. Weather is the main reason I ruled out a quad also, too
much freezing rain during the winter.
Secondly, the SteppIR is too expensive; I could stack 2 T-8's for about
the same price. Additionally, my operating style is one of jumping from
band to band, and I don't want to have to tune my antenna every time I
change bands, even if it takes a short amount of time. I think that would
get old rather quickly.
Like transceivers, all antennas have pros and cons, what works for me might
not work for you. I just want an antenna I can put up and pretty much
forget about.
