Right Jim. When I said "resistance" in relation to the radiator, I was speaking of the radiation resistance of a self-resonant (i.e. non-reactive) radiator.
Perhaps that's what has added to the confusion. The radiation resistance of the "radiator" is in series with the resistance of whatever ground system is being used. The RF power is divided between them according to Ohm's law with the higher resistance absorbing the most power. So the challenge with a monopole antenna is to have the radiation resistance of the antenna as high as possible compared to the resistance of the ground used. 73 Ron AC7AC -----Original Message----- most of those posting have confused feedpoint Z with radiation resistance. There's a nice graph in the ARRL Antenna Book showing radiation resistance of a vertical as a function of height. 73, Jim K9YC ______________________________________________________________ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
