A couple folks in the Virginia Tech ham club are considering adding
omni-directional receive antennas for 6, 2, and possibly 432 (and 222,
once I get my xverter running) to augment the modest yagi farm used in
VHF/UHF contest. I agree that having something omni to switch to during
search-n-pounce periods could be advantageous on bands where we're using
boomers now. I've built a few 2 meter squalos for singleton mobile use
in the past and they've worked OK... but I would think stacking bays of
these would be in order for a little more gain in a contest. It seems
I've seen posts where folks have mentioned such arrays before on this
list.
Any suggestions/war stories/words of wisdom for constructing and using
such a beast? Is the stacking theory a little overboard? How many bays
do the big guns run? Is it worth building them for 432 and above (sans
the dish and horn bands)? End-fed vs. center-fed? How about noise
considerations? Anyone doing half-wave spacing for the lower angle --
experiences?
Thanks, and CU in the 432 sprint!
