How in the world does that tell us anything about transmission lines? -- 73, Cecil, W5DXP 1 Am I getting sucked into the bottomless black hole of transmission lines? Yea, I care! If I want to test or tune my transmitter or amplifier and need a dummy, I use dummy load. When I need to radiate killer signals I use my Razor beams, but they are designed to have 50 ohm impedance and broad bandwidth (possible, been there, done it) no matching crap, no reflections (ok very small) and I don't give a Freak about nurturing reflections on the line. I hate reflected waves and I suppress their generation/reflection/travel and endless discussions about problem that nobody wants. 2 Huh? You haven't figured that SWR is bad for transmission lines? All I want to know about transmission line that it doesn't have impedance bumps, keeps its impedance, that it has lowest possible loss and doesn't radiate or let the water in. (That goes for open wire feeders too :-) Oh, color doesn't matter and it should be repulsive to chipmunks and other SWR ignorant critters. Why is this endless argument about reflections going on? We know they are bad, we know how to eliminate them, so what's the problem? You love them so much that you want to keep them in your coax? There are no reflections around this shack, only in the mirror of my ugly face after 48 hr contest. OK hit me now that it is impossible to have reflectionless antenna-coax-tx. My answer, yea, there are some (very little) and they are insignificant to me to worry about and lose sleep and hours at the keyboard. Ins't it like eunuch dreaming about sex? :-) SK 73 Yuri da noSWR BUm |
