You could try a box kite,
or a tethered balloon.
An interesting project would be a computer controlled kite
servoed to hold a constant position.
Or a sky hook?
What about a remote site with a radio or laser link to your QTH?
The more ideas that you start with the more likely you will find a
good solution.

ROHN 9H50 34 Foot Telescopic TV Wireless Antenna Push Up Mast
Interesting suggestion. Rohn is well known to me, though I don't
typically think of them for things like push-up masts.
For those suggesting 6-10' of pipe, at my rooftop I get a reception
cone of about 50 degrees elevation and above during the vegetated
months (say, mid-March through mid-November), and about 30 degrees
and above in the dead of winter, due mostly to dense tree cover
that is 60-80 feet tall. So, I'd really need to get 20 feet +
above the chimney (50+ feet above the ground) for a significant
improvement. The suburban residential lot size doesn't leave me
much to work with (no centrally-located tower, therefore no guys
unless I negotiated easements with the neighbors, and Hell will
never be that cold...). I doubt I could get a permit for 80' of
Rohn 55. Maybe if I put a wind generator on it....
Thanks again,
Charles
