   Yes, but here all you have is mast and antenna exposed to wind.  With
a roof mounted tower, aka Glenn Martin, the tower and rotor are exposed
presenting many more angles for the wind to generate vibration and noise.
It looks like some rubber sheet in strategic locations would further
reduce any vibrations transmitted through the frame of the house.

   In my case, I have room for ONE 90 footer and that's about it.  This
presents a practical support for 15 and 10 meter antennae and allows me
to increase the size of the 20/40 beam on the 90 footer.
