[Towertalk] Antenna Spacing on New Tower

[Ed Williams]

I will be installing a US Tower TX-489 and planning to install the following
antennas


1. New KLM 10-30-7 LPA 1' above the tower (30' Boom & 8.25 sq ft)
2. Hy-gain Discoverer 7-2  40 Meter 2-element Beam ( 22.6' Boom & 6.0 sq ft)
above that
3. Diamond 500HNA 144/440 vertical (17.8') on top


 I have a 6061-T6 2" x 24' aluminum mast and my question is what spacing is
needed to insure no interaction between antennas and should the beams be
rotated 90 degrees to each other or could I keep them in the same
orientation.
