Yes my inverted vee's were resonant.

Again, I had relays that opened up the feed points of the unused
antennas.  EZNEC will show voltage induced, however, a floating
quarter wave will not experience much current, and what current
it does experience will not radiate much power, because of the low
radiation resistance.  The unused antennas might as well not be
there for all practical purposes.
