TopBand: rohn 55

[Skip Riba]

hi all looking for suggestions for a shunt or omega match . i have no idea 
where to start to create a vertical transmitting antenna from it.
here is the description   its a 10 sections of rohn 55 18in face with a 
force 12 rotatable dipole for 80 and a 12 foot mast sticking above the top
of the tower dipole mounted on to just above the head of the tower
and a 22 foot fiberglass snake for 460mhz at the very top making it close
to  144feet overall
am looking for a way to put a good ground system in but make it a effective
transmitting antenna for the top band as my inverted vee offers me little
in pile ups 
thanks   best 73 to all
