[TowerTalk] Beam Interaction TH-7DXX & A3WS

[Bernard(wtrone)]

    No, I didn't see much in the way of interaction.  The VSWR curves and
the "patterns" looked like they should.  Before I put the CushCraft up, I
did a little analysis for the spacing and "observed" that about 10 ft looked
good.  Of course, this analysis was with charts in the antenna books, not a
computer program.

            73,


            Bernard, WA4OEJ
