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).
