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
10/15/20M tribander without serious interaction?
