Series resonance problems in the plate choke in multi band tanks are solved by moving the plate choke towards the lower impedance antenna output end. This way the plate choke is only part of the output tank on the lower bands. The con of course is requiring a higher peak voltage rating for the band switch and first plate tuning capacitor.
