Javier if you have some space around your tower and it is in the clear, I
will lay same radials and shunt fed the tower with the TH6 as top loading,
it will work the same as your vertical. If not. I presume you will have to
detune the tower ( I think for this setup will resonate at or near 80 m
band) with also a shunt fed plus capacitor, tune for maximum current on
shunt wire.
