Topband: Beverage Antenna Tuning

[Ashraf Chaabane]

Mark,

I'm planning to have the termination value adjustment excercice for F/B
maximisation using a BC station signal. However, does SWR measurement have
to do also with the termination value? Or that's rather the matching
transformer that I should act on?
I now have an antenna analyzer and multimeter. What kind of optimization I
can carry out? (The beverage is permanently installed).
