[Antennaware] Tribanders on 12m/17m

I've owned a Hy-Gain Explorer 14 and now have a Cushcraft X-9. Both worked 
on 12M; the EX-14 even had some F/B. Only used them a few times to work 
DXpeditions when another antenna was not available.

Neither worked on 17M. I'm sure the beta match on the EX-14 looked like a 
short circuit across the high impedance of the off-resonance d.e. The X-9 
with it's log cell loaded up OK on 17M, but was quite deaf, so I suspect the 
radiation pattern was very high angle.
