I have my SKYs mounted now. 
On my house I just used a chimney mount and the fiberglass pole from an old pressure washer extension handle. I put part of a rubber hose around the pole where the clamps go. I figured that the foam grip would reduce vibrations. So far I haven’t had any false rain alerts from it so I’m going to paint the pole to protect it from UV damage.
I also have my second one mounted to my RV. I bought a pole mount and tall flag pole from polesandmore.com. The pole is made up of several slightly conical sections of fiberglass poles which friction stick. The first three inner sections have a pin to make sure the pole doesn’t collapse. The base of the SKY wouldn’t fit on the 4th section (3rd and last pinned section) so I have it on the 5th section. It fits a little loose but doesn’t appear to wobble. If I don’t get any false rain alerts from it I’ll put some tape around the pole to snug it up a bit.
