You are correct in assuming I dont have written permission, and I'm having second thought on putting something up there.  I'd hate to invest in installing radials then be force to remove it at some point. 

I'm starting to link about hanging something between my house and a couple of the tree limbs on the other side of the fence.
That'd be alot more stealthy and less work to take down if it became an issue.

Maybe a 80m loop (for skywave) or Carolina Windom or G5RV?

I got my RFI down to about 1% of what it used to be my using some
Fair-Rite mix 31 "Biggest Clamp-ons" from
I wrapped the powercord and speaker wires of my stereo receiver around it 6 turns, and RFI dropped to almost nothing.
I also got one on my antenna feedpoint with 7 turns to reduce the common mode currents. 

With my RFI down, I'm back to considering a ground plane vertical above my chimeny, like the Zero-Five with it's built in radials system(
I had tried putting the S9v31 up on the roof with 4x 20m and 2x 40m radials and 40m was so noisy, it was unusable.   

My DX-CC clone is working pretty good within the US, I just think my DX is limited with it.
I hear Japan, Australia, and Argentina often on 15m, but barely ever Europe, probably because the hillside
is killing the DX angle.

K7JQ, I like your setup of the screwdriver on the hill, stealthy and RFI clear. The top of the hill is probably 1/4 mile away for me.

Anyway, thanks for the feedback.
I have yet to join a club in my area, just moved here 1 year ago. It'd
be nice to find a fellow ham I can borrow some antenna's for testing.

Lots of local clubs to visit and join:

Anaheim ARA
Downey ARC
Fullerton RC
Orange County RC
Pasadena RC
Rio Hondo RC
South Bay ARC
Western ARA

Friendly folks, check 'em out.  They all have monthly meetings.

I have my Cushcraft R8 mounted on a 10' tripod and a short mast (another two feet) 200 ft behind my house with about 275' of LMR-400 running to it. No radials.

It works like a hose.

170 countries worked in the year and a half since I got my vanity call using that antenna exclusively. Don't spend a minute worrying if the long run of coax will be a big problem. It won't be.

When all else fails, try the simple.
Your hill may block some signal, but you can still get a signal over it.
Then you can try getting stations in the shadow via bounce.
I lived in an RF swamp down in a valley years ago, and I was able to get out when the ionosphere cooperated.
But I would avoid using someone else's property, especially without permission.
Look at antennas you can get a high take off angle on, or even one that can shoot straight up.
For the other directions, low take off angles can still be used.
One good antenna is the dipole over a good ground plane of parallel wires slightly longer than the driven element at 1/4 wave.
It acts as a 2 element beam shooting straight up.
I would still install a ground mounted vertical with a good radial field for all the other directions.
Good luck!
