[Antennas] Antenna Spacing Question

[Chris Boone]

OUCH!! Two metal verticals less than 1/4wl spaced will have effects!!! If
you could somehow have an insulated mast from the ground up (OH wait YOU
DO!! :) it may not affect the DX_E antenna...Get it AS FAR AS POSSIBLE since
you will have the mass of metal on top of the fiberglass.....and you will
have the loop coming off it for 80 and 160...THAT will affect the vertical
more than anything..

Hello to all,

I have a 43' tall DX Engineering vertical installed at ground level in my
yard with 40 x 40' long radials installed on the ground.  I am getting ready
to install a hex beam on a military fiberglass mast.  The mast will be at
least 50' high, so the beam and rotor will be above the top of the vertical.
 I plan to use this same mast for installing a K9AY loop for 80 and 160
meters.  My question is this: how far does the new antenna mast need to be
located away from the vertical so that it will not interfere with the
performance of the vertical antenna, which will be used for 40, 80, and 160
meters only.

Thanks in advance for your input.

73,
