Like they said you cant have both, but if you can do 25 feet around
the antenna, then try a HF9V. At 29ft it is under your 30ft height.

Lay out about 16-32 radials of 25 feet under it in a circle and you
have a nice multi band performer. You still have to pick 75 or 80 on
it but with
a good tuner you can do most of 75/80 curve. I love mine and its in
a limited area behind my house.
