==================================

Wrong ! The antenna 'System' IS resonant, by definition, if it has a purely
resistive input impedance. If that interfering nuisance of your fold-back
circuit springs into action then it means the pure input resistance is
something other than 50 ohms. But it is still resonant.

Reg, the chances of a foldback being caused by a resistive antenna is
about 1 in 360. Actually less than that because the transmitter will
not fold back between 25 ohms and 100 ohms.
