Dave,
Great idea. There should indeed be a market for a 50/144/432 tribander, if
it's practical. The $130 Elk 144/432 single feed line duobander is only 2'
long and works like a bandit on the satellites. Not sure what it would take to
extend this log periodic to 6m.
One thing with Joe706ers who would like to try VHF but can't afford an antenna
is to remind them to try their internal antenna tuners on 6m. When my 6m yagi
went down, I tried 6m with my HF vertical. With the tuner, it worked fine.
Not nearly as well as a yagi, but well enough to work South America when the
skip came in. And of course, when there's skip a simple 6m dipole works
wonders.
Also, while new commercial antennas and coax are pricey, there are a lot of
used ones that can be had for little or nothing. I put an ad on the reflector
of my local club that I was looking for a 2m yagi and got 3 replies - 2
offering me one for free and the other offering me one for $20.
