I know I'm not the first one to observe this... I have a KT36XA on one tower, and reference monobanders for 10, 15 and 20 on other towers. On 10 and 20, the XA always performs within a few dB of the
Hi Steve, I've used NEC to study the possibilities of interactions like this on other bands. The method is pretty simple. Build a model of a simpler antenna like a 2-3 element 15M Yagi, and add a 40M
I seem to recall reading about 15m SWR complaints but not gain. The KT36XA is a very complicated antenna. If it always acted this way for you perhaps a component was out of spec. Many 40m beams are n
Hi, Steve. Depending upon the antenna, I don't think that SWR necessarily correlates all that well with gain. A better test might be to monitor some distant stations with the XA and rotate the 40 to
I bought a KT34X from W3TMZ in 1981 and through 2 upgrades made it a KT34XA. I got tired of the amount of upkeep required and sold mine plus a KT36XA upgrade kit to NQ4I. My antenna wound up at W4
Steve, I don't know why it stinks, however, the way I test antennas here MAY help you determine if the 40m beam interacts or not. (yes, I read what you said about SWR) What I'd do is get on 15m midda
