Horizontal antennas below about a half wave are cloud-warmers. I had one 
at 120 ft, and my vertical nearly always beat it, often by a LOT. Stick 
with the vertical, with radials or some sort of counterpoise, of course.

I recently did an NEC study of exactly this question for 20, 40, and 
80M. 40 and 80M results scale by a factor of 2, and 80M results can be 
scaled by a factor of 2 for 160M.

There are some ideas about non-conventional radial systems in
