Non-Penetrating Roof Mount with Adjustable Collar for Antenna, Mast, Satellite Dish, Helium Radios

I utilized Gray Concrete Top Caps, each measuring 6 in. x 2 in. x 16 in., and weighing a total of roughly 64.46 lbs (sold separately), to securely anchor a 10-foot mast (comprised of two 5-foot masts joined together - sold separately) atop the awning covering my balcony. I highly advise using a rubber mat (sold separately) to safeguard the surface underneath. For enhanced stability, I drilled additional holes in the mast and used M8x30mm stainless steel bolts and nuts (sold separately) to firmly attach the mast to its base. This configuration, shown in the photo, is located on the 6th (and a half) floors and successfully endured wind speeds surpassing 60 mph in Fremont, CA, on February 4, 2024.

This item is for light-duty use only! The base is not big enough to safely support a mast over 5 feet. I used 6 full-size cinder blocks weighing 30 lbs each and it blew over in the wind. In addition, the clamp that holds the mast upright is held together with rivets! They stripped out under moderate pressure.

WYSIWYG. Mast mounting hardware not included. Will fit 3" pipes by removing half the nuts that secure mast. Use liquid thread lock as alternative.
