Rick,
I have had good results using inverted V and slopers off the tower. I placed
insulators in my upper guy wires and feed them with a single 50 ohm coax at
the top apex. The shield is bonded to the tower leg at the feed point. I
have tuned them to 80/60/40 & 12m.
If you tune one of them to an active band covered by the beam, it might skew
the results. I have never done that so can't provide any insight. However my
40M sloper works on 15m and does not seem to interfere with the 15m beam
pattern. But that's just a non-engineered observation.
