Non PenetratIng TV Antenna Flat Roof Or Shallow Peak Roof Mount - Needs Covering

Description

Please note that the tools shown in the photographs are not included.
Maybe a coating product like Semco Liquid Membrane could be used to weather-proof the plywood (or, at least make it weather resistant).

Full disclosure:
It is also listed on the San Francisco Bay Area Craigslist and I do not collect sales tax.
This unique mount will work on a flat roof or a horizontal surface like a balcony or straddling a peak roof depending on how the four lag screw feet are adjusted.
I also have a custom-made large wood flat surface mount for sale. Please see my other listings.
The box mount dimensions are 18 x 18 x 8 inches and is constructed of heavy 3/4-inch plywood. It weighs about 13.6 pounds.
I have three (3) or maybe four (4) available to sell.
The masts and antennas in the photos are not included.
Non penetrating antenna mast mounts for peaked roofs are expensive, from about 0 to 0 shipped, and because they are primarily made for relatively short J pole mounts for satellite antennas you still have modify them to add a mast anchor to attach longer TV antenna masts to them.
If you’re looking for a more esthetically pleasing alternative to antenna tripod mounts this custom made plywood “birdhouse” mount is good. Tripod mounts can straddle peaked roofs but on very steep angles all their feet may may not rest squarely but that isn’t an issue because the objective is not to penetrate the roof.
(The lowest price for a 3-foot tripod mount is about shipped.)
A woodworking friend made these antenna mast mounts to straddle my home’s peaked roof. The included four (4) carriage bolts should be added to each bottom inside corner post by drilling 1/2“ holes and screwing them in with a 5/8” wrench and then adjusting them after placing the box on the roof so it makes solid contact with the irregular shingles surface and the degree of roof pitch and to prevent the wood from making contact with the shingles. They also allow rain to drain away from the mount.
My friend said the best way to make the boxes weather resistant is to cover the outside surfaces with plastic panes that are cut to fit.
There is a universal roof/attic mount attached inside (the lowest price on eBay is shipped). The mount U-bolt can clamp masts up to 1½” in diameter but the box top hole may have to be enlarged if the fit is too tight.
The two U-bolt nuts are tightened by using a 7/16-inch or 11mm deep socket wrench with a 6-inch extension through the holes in the side. There are two extra “peep” holes on the top next to the mast hole so you can see the U-bolt nuts to guide the socket wrench to them.
If your mast isn’t taller than about five (5) feet and your antenna isn’t susceptible to high wind loading you might be able to put concrete blocks around the mast instead of installing guy wires. However, that might be a code violation. In California it specifies that TV antennas must be mounted according to the manufacturer’s recommendations and they usually don’t include non penetrating mounts that are typically for satellite antennas. I know about this because I received a code violation citation when a state inspector for a house in my neighborhood saw that my antenna at that time had a five-foot mast instead of a J pole. I had to remove the blocks and install guy wires.
For local pickup I am a few blocks off of 680 on the border of Pleasant Hill and Concord, California.
