Re: sBitx antenna-first warning


 

Not sure which statement that would be.
I've been making lots of them.

A resistive SWR meter assumes that the transmitter wants to see a 50 ohm resistive load,
but the transmitter will not necessarily work best at exactly 50 ohms.
For example, assume we are operating at 30mhz and there is a long trace to the antenna connector.
The antenna system would want to have a little bit of capactive reactance to counter the inductance of that trace.

Not much point to worry about such minor issues.
We just need a reasonably good match between transmitter and the antenna system,
doesn't have to be perfect.? You could spend a career trying to understand everything
that could go slightly wrong here, many people do.

Jerry,

A resistive bridge SWR meter should not work if this statement is true.

Am I missing something here?
