Hi Tom -
I would be afraid that with the ends that close together on 80 that, at 
least up near the feed point, it would start looking too much like an 
unterminated feedline, or at best be directional in the direction it was 
pointed.
My vote would be to make it an 80 foot centerfed vertical with 20 feet of 
horizontal loading on each end. There  would be very little current in the 
end loading parts so it would look mostly like a nice omnidirectional low 
angle radiator without need for radials. Hopefully you could keep the bottom 
20 foot loading wire at least ten or fifteen feet off the ground. That 
should work quite well. You've got quite a bit of height to work with so I 
tend towards the end loaded vertical rather than the inverted L, since it 
would give you more "vertical current".
Good Luck !
Gene / W2LU
