YMMV, I can hear it in that part of the house when I run the rotator, but
don't hear anything when the wind is blowing things around.
17.5' Glen Martin on the roof, internal bracing tied to a load-bearing
wall, with a Ham II rotator on top.

When I lived in Dallas TX, I had a Ham II mounted in the attic with
the mast extending up through the roof where my 5L 6M & 10L 2M beam
were mounted. When I turned it EVERYONE in the house knew. Also I
had 40' of Rohn 25G mounted with a House Bracket with a 16' boom
Sommers antenna on it and it could be heard even when not turning.
Every gust of wind caused it to moan and groan and whistle, and
like the 6&2 combo, everyone knew when it was turning.
When I moved back home to Kentucky, I made sure all my antennas
were NOT affixed to my house, other than by cable..
YMMV

When you run the rotors on a roof tower like that do you hear it in the
house?

braces. If the antennas go, the roof will go with them... ")
