[TowerTalk] TWO VERTICALS One Fed 90degrees Behind The Other

[Dave Jordan]

Hi Folks,

I recently installed two Butternut HF6V vertical antennas.  I spaced
them at a quarter wavelength for my favorite spot on 40meter (7.277Mhz).
I tuned each ant.
to resonance (with MFJ259B/ separately on the same frequency). I cut a
three quarter wavelength piece of RG213 to use as the delay line between
the
two ants. When I check the resonance at the input side of the array the
resonance spot is now around 7.450Mhz. I checked at the shack and the
results are the same...

SO, my question is WHAT HAPPENED? Should I tune the antennas lower in
freq?  The ARRL ant. book makes no mention of this weird scenario.

thanks,
dave
