Its not clear to me why one would need to put the sense element at the antenna. About the only benefit to it that I can see is you can make sure your coax to that point has not become extremely lossy. Just about anything else can be measured with the sensor in the shack. One would be more interested in knowing the SWR looking into the feedline at the transmitter than at the antenna end. If an automatic antenna tuner is near the antenna feed point, if its working then the SWR should be low in the coax from the tuner to the rig. Trying to read the SWR between a tuner and antenna is not all that useful and many swr sensors may not be accurate when not used in 50 ohm feedlines. I didn't quite say that right. Between a tuner and antenna we would expect a high swr and the feedline not matching the Z of the antenna. If the antenna is resonant, then a tuner would not be needed. So I am missing something, perhaps someone could fill me in! 73/72 - Mike WA8BXN ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net
