ok – sorry – stub.
Specifically adding something to a 4 element 40 to eliminate 15 meter
interaction? I believe Optibeam does this – not sure how they do it. Is this
just using the element with a parallel line tuned through a cap for max current
on 15? If so any suggestions on how long to make it and where specifically to
put it on each element 1/2?
Or is there a way to use a relay, open normally, closed when on 15 that would
add some impedance to the antenna causing it to be detuned at 15?
Alternatively I can rotate the antenna 90 degrees but boy it would be so much
better not to have to do that to avoid interaction on 15. thanks in advance,
Gary K9RX
