I would also recommend using a rubber barrier non-slip matt under the mount, I’m assuming your ballast will be concrete blocks this will also be more forgiving to the roof surface too .

I would suggest using fiber if able and take Sam’s points to heart as well. Proper sealing and grounding will keep your install working for years instead of months.

Those outdoor units can be hefty. That is unless you're using extension cables to hang the AP inside with the antenna outside. In which case, proper sealing of all of your connectors, lightning arresting, power protection, etc are all good 'non mount' gotchas you're going to want to consider. -Sam On Mon, Aug 8, 2016 at 7:06 PM, DAVID BEYERLE <deb...@psu.edu<mailto:deb...@psu.edu>> wrote: Ken, First calculate the wind pressure from the antenna using something like http://www.wikihow.com/Calculate-Wind-Load<https://websitecheck.quinnipiac.edu/canit/urlproxy.php?_q=aHR0cHM6Ly91cmxkZWZlbnNlLnByb29mcG9pbnQuY29tL3YyL3VybD91PWh0dHAtM0FfX3d3dy53aWtpaG93LmNvbV9DYWxjdWxhdGUtMkRXaW5kLTJETG9hZCZkPUN3TUZhUSZjPTZ2Z05UaVJuOV9wcUNEOWhLeDlKZ1hOMVZhcEpROEpWb0Y4b1dIMUFnZlEmcj1yWWZxSF84b1R2Y1h4UnhVSTN4M20zWTdOd2dpcjd0bnVvR2JkWnNyVU00Jm09QmRqV3pvVlZYNVFzNWJjOUlpTDZPNGdCVXpCUzBLYm1yc1ppLWRiZDBhWSZzPVhCNnJMLWViZG1YQmVmY253VEFONDlxSk5KWk02eVIxUHBvT1RjcEE0YVUmZT0%3D&_r=cXVpbm5pcGlhYy1lZHU%3D&_s=ZGtyZXlub2xkcw%3D%3D>. A wind load of ~25 lb for that antenna should be very conservative. Then sum the reactions (torques) at the base of the roof mount...the antenna imparts an overturning moment of ~250 ft-lb at the mast base, and so you ballast the mount to compensate for this. The base of the frame is ~3' square, so the center of mass of cinder blocks which you'll use for ballast will be ~1.3' from the base of the mast, suggesting 180 lb of ballast should be enough. Many installations use considerably less ballast and get away with it. I happen to not like my masts to move (much). The "gotcha" you should be aware of this that your roof must be able to support a ~200 lb load over an area of ~6 sq ft. Of course, if it supports you, it likely will support the loading of this assemblage as well. Best, Dave David Beyerle, P.E.
