More on these stubs. Say one station is on 15 and another is on 40. There is no way for the 15 station to block the 40 station signals is there. All one can do is to insert a 15 stub on the 40 statio

Thinking about that logically, it appears it would still pass 40 meters to me. The reactance of a 30 degree shorted stub is the same but opposite sign as a 60 degree open stub. The result would be a

Stub combos are very easy to model in Elsie. I like using that because I don't have to remember what the various combos are. The Elsie coax is "ideal" and as such it will show really huge attenuation

Real stubs in real systems can have over 15 dB variation in attenuation, depending on electrical spacing from the antenna, and a lesser extent spacing from the amplifier or radio (which usually is d

That's what happens when you don't have the reference in front of you W2VJN's Type 4 stubs (page 34) - keeps 21 MHz out of 7MHz - 1/4 wave 21 MHz open ended and 1/2 wave 21MHz shorted teed - this put

... ... In my systems the 40m signal entering 15m is attenuated by band filters. Even ICE with old school micas is OK, after which FT1000MPs survive no problem. I use always band filters if I have m
