What I have is a 6 foot roofer...the rotator base sits 24" down from the thrust bearing mount surface.....Can't get much mast down in that setup. As much as the wife is gonna grump, I think I will off the 6 footer and get a 9' Glen Martin roof top. (45" from rotator base to top of thrust plate) Should give me a lot more stability on the mast above the thrust bearing. The antenna I am going to swing is a Hy-Gain THX3-MRK4..not really big...14' boom, 15' radius with 28' element.
I **would** like to use a mast long enough so I can also swing a 40 meter rotatable dipole, but the separation between the two antennas may be a show stopper.
(Sure wish she would let me put a tower up. Fat chance..the antennas embarrass her. No...I am not gonna get rid of her...we have been married for 44 years...she put up with my antenna farm when we lived in the country. She doesn't want another here in our sub-division! LOL.)

As far as you can. I went 10' in for 13' out. But it is up to you.
