Here's a thought -- if you put a isolator between the PA and the duplexer,
and a isolator between the duplexer and the antenna, wouldn't your
duplexer see a near perfect 50 ohms at all times?
I've heard one local ham talk about his theories of repeaters, and he
strongly supports making sure the SWR is as low as possible. I used to
think he's nuts, then I realized there is some truth in that -- at a
minimum SWR, the antenna is as close to matched as possible, even if that
is slightly off frequency. It makes sense to me that if the PA is
expecting a 50-ohm load, and the antenna is 50-ohms, then the SWR will be
1:1.
Comments?
