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.
