Why not a metal tube on the end of the elements. The tape slides inside forming capacitive coupling. Remainder is two coils one in parallel with cap and an end load. A bit of capacity hat to limit co
Well the coaxial capacitor seems to work OK when modeled. Messed around with it this AM. It's basically some loading on the end of the element with an adjustable coaxial capacitor (their tape in a me
