I'm having trouble envisioning this, Bob.
It doesn't say if he wanted a base antenna or wanted to go mobile. In
the case of mobile I would recommend the Radio Shack Elevated-feed 5/8
over 1/4 wave Cellular antenna. I've used mine for about five years and
it still works like a champ.
As far as base goes, the trick is more to keep the coaxial cable as
short as possible and to use low-loss coax like Belden 9913 - or
better. A discone is a good all round antenna but even the RS antenna
above stuck on a tower will outperform it on 800MHz.
