How close vertically on the same mast can a new CC XM240 be to a big 10/15/20M tribander without serious interaction? Marsh, KA5M _______________________________________________ _____________________
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
Dave I guess that it is all a matter of antennas and situations. I put up a XM240 at about 133 feet above a Force 12 C3E at 120 feet or about 13 feet apart. The interaction between the two was fairly
Wasn't there something said years ago about grounding the reflector on the XM240 so it would work like the earlier 402CD? I can't remember if this was intended to reduce the interaction on 15M or if
When I was in Montana, I had an ungrounded XM240 and every time a storm would brew up you could hear the sprarking between the element and the boom in person and obviously on the radio. At night you
I have to apologize for my previous posting on this subject that said I had an XM240 6 feet above a KT-34XA. My 40 Meter antenna is the 40-2CD, not the XM240. I got the model numbers mixed up. Sorry
Interesting Mike ? I replaced my Hi Gain 3 element with an XM240 and it's insulated elements gave me no top loading for my shunt feed tower ( only boom @ DC ground) Question ..... Di the grounding ha
I don't believe that there was any change to the swr curve or FB. I believe that one of the Cushcraft Engineers said that grounding the Reflector was ok. It might have been by someone who modeled it.
