After a fair deal of work, I've tuned my Tram-Browning through-glass antenna to an SWR of about 1.2 at 465 MHz. So now my question is, what about other losses? SWR, as I understand it, is measuring the transmitted energy that bounces back to the transmitter, but that can't be the only potential power-loss mode for transmission, right? Resistances must also play a part, as well as some of the bizarre LCR effects I vaguely remember from my circuit design class several decades ago, right? I'm assuming the inductive coupling in the through-glass transducer must produce a loss too, given the distance travelled through a dielectric...
So how do you measure these losses? Obviously SWR is most important, what with how it can burn up your radio, but I'd also like to know how to measure the real power making it into the actual transmission...
