Yes, a good point that I neglected. This entirely circumvents my yammerings about reciprocity. Reciprocity is a characteristic of a single pair of ports in a network. Introducing separate receive antennas can surely cause a one way effect. Consider what happens when I hook up a dummy load as a Rx antenna ...
73 and thanks for listening, Carl WS7L I've often thought that some "one-way propagation" is simply due to the > differences in antennas. For example, two stations with the same power, > ambient noise level, etc. are receiving on Beverages pointed at each other, > but their TX antennas have different takeoff angles and/or patterns. _______________________________________________ Topband reflector - topband@contesting.com
