Although I agree with most of the preceding, the above statement hints at a common misunderstanding. In general, you do not want to feed an antenna from a source impedance that is the the complex conjugate of its impedance. Doing so guarantees that you cannot exceed 50% efficiency. Whilst such matching will give you the highest power for any given open circuit voltage, it will not give you the highest output power for a given input power. When one says is a transmitter is matched to 50 ohms, one actually means that its output network presents the optimum load to the finals when feeding a 50 ohm load. -- David Woolley "The Elecraft list is a forum for the discussion of topics related to Elecraft products and more general topics related ham radio" List Guidelines <http://www.elecraft.com/elecraft_list_guidelines.htm> ______________________________________________________________ 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
