[TowerTalk] CC XM240 above a big Tribander

[Dave Hachadorian]

My XM240 is six feet above a KT-34XA.  The booms are aligned.  It
works for me.

After you get the antennas installed, run a f/b ratio test on the
tribander.  Front-to-back ratio is easy to measure, and is the
most sensitive test for adverse interaction.  Here is more info:

I just noticed an error in the last paragraph of that 2006
posting.  The last paragraph should read,
"Sometimes just changing the length of the 40-2CD's feedline, or
shorting/opening its feedline when the antenna is not being
used will solve interaction problems."

How close vertically on the same mast can a new CC XM240 be to a
big
10/15/20M tribander without serious interaction?
