The best antenna for receiving is the one which produces the best signal/noise ratio at your station. The two are often different, because they're determined by different antenna characteristics. So for starters, you can have two "best" antennas for each station you want to contact, and that "best" will vary with the skip elevation angle, local noise level, and directions and angles the noise is coming from. Just was I was thinking when I prompted the "works" definition. I should not be surprised if many observations indicate the better antenna for tx is different from the better antenna for rx. I am not trying to question reciprocity, but there are several factors, ambient noise at the rx site probably being the most significant. Key thing is, works is not adequately defined by making one or a few DX QSOs!. Mike, perhaps you need to formalise your "works" criteria with your current experience, identifying what you need to record, before making too many more observations. I agree with Roy, for each antenna, rx main figure of merit S/N (crudely S units between ambient noise and signal), and on tx, the other stations observed S meter reading. (Whole log of issues there... but a rough start supported by the current RST reporting scheme.) Owen -- |
