Hi Guys,
I had great results with a SteppIR 3-element up 60' when the antenna
worked as designed. Unfortunately, the Controller was bad upon arrival, and
then an 80mph windstorm blew two fibreglass elements off the antenna which
then allowed water into a Stepper motor and it went bad!
Perhaps I'm a glutton for punishment but I'm seriously considering a
2-element SteppIR at a temporary QTH in the Midwest as the 3-element SteppIR
turning radius may not clear the trees. Question: isn't the short 6' boom on
the 2-element SteppIR too short for good results on 20-meters? I am not
familiar with using modeling programs and don't have the time to learn so I'd
appreciate your thoughts on this.
A 3-element tribander will work at this temporary site as it has about the
same turning radius as a 2-element SteppIR... and a Tribander like the
Hy-Gains TH3 might perform as well or even better better on 20-m. (on the
portion of the band that it is tuned for) as it has a little longer spacing
between driven element and the reflector. Of course the Tribander would be
alot cheaper too.
What's your thoughts on the efficiency of a 6' boom length for a 2-element
20-m. yagi?
Thanks for your thoughts!
73,
Dick- K9OM
