[TowerTalk] New project

[Its from Onion]

Ok guys, new project time.  

Rohn 25  3-10 foot stalks with a 9 foot top section.
base is a concrete driveway.  Next to 2 story house.
Antenna is a TA-53 14' long at 55 pounds.
Rotor is a Yaseu 450.  (thinking too small)

Questions;
1. Should I attach to house or guy?  
2. What is un-guyed height for 25?
3. Base plate Hilti bolted into driveway or cut driveway and dig hole.
4. Don't want 2 inch copper strap running across driveway.  Alternate ground ideas please.

The big question is grounding.  If this was in a field I know what to do, but since I'll be in the middle of a 
driveway it's a tad different setup.
It would be nice with no guys, but also the same bolted to the driveway instead of a 2x2 hole in it.

Thanks in advance.
