Skywalker 12” Heavy-Duty Wall Mount Pair for TV Antenna Mast with (2) Brackets with Lag Bolts

If you mount this correctly, this is sturdy enough for a 2 meter antenna in a 120 mph wind. It's 11 gage steel which is .105" or just under an 1/8 of an inch which is perfectly adequate for this application. You do have to mount it correctly and use serious, larger, American made fasteners if you really want to do a lifetime quality installation. I did not have to bend anything, everything fit reasonably well. I replaced the fasteners with 1/4-20 stainless steel bolts and added flat washers. Lock washers don't do anything on sheet metal parts like this and will make it more likely to loosen up, not less. I replaced the wall lags with 5/16" x 3-1/2" long stainless steel lag bolts. I did not want to bend the legs and the center to center distance is 10-1/2" so I used a couple 2 x 6 pieces between the studs inside to get a good lockup with the lags. You can't expect these things to come with oversize, top quality bolts and lags so for the price, I think these are a great buy. Not going to try of course but I'm pretty sure I could stand on the 3 leg bracket, that's how solid it is. Only con is these are not deburred very well. They have very sharp edges in places and little micro slivers of steel all over, use gloves, preferably leather gloves! There are no instructions but it's three pieces, I think you can figure it out.

I saw a number of reviews that mention having to bend the brackets so the feet on the 3-legged bracket sits level on the wall. I found that installing the 3rd leg in the bottom hole, and adding (2) 5/16" washers between the two halves of the bracket at the top hole makes it sit ALMOST perfectly. The problem other mention is caused by the addition of the third leg between the two halves of the bracket. I imagine that if it is installed on the outside of the two halves, there would not be a problem. I wanted to install between for added strength in both directions. The brackets are strong. The 1/4-20 bolts are standard cheap grade "0" hardware. A 7/16" socket or end wrench fits these. The lag bolts, as also mentioned in others' reviews, are cheap too. I intend to drill very small pilot holes to prevent bolt heads from snapping off, and using a 3/8" socket to drive these into the studs. I am using 1/4" lock washers under the lag bolts (overkill) and the nuts of all of the 1/4-20 nuts to ensure they do loosen. All in all, great brackets for their cost!

Assembly required, but very easy. The included hardware is of as expected quality. Good value for the price in my opinion.

Solid brackets that went together easily. Been nice if they’d come with washers and lock washers but since I knew that in advance I was ready. I mounted mine on unistrut to get the mounting on 16” centers, which worked well. I didn’t use the self tapping screws to secure the bracket to the mast, drilled a hole through my mast and put a long bolt in instead, so I could adjust the diection the cell booster antenna points in Frye future.

If you need to screw an antenna to the side of a building here's the simple, affordable, and sturdy solution. I'm using them to hold an 10 foot mast on the side of the garage with an ADS-B aircraft receiver antenna on it. Couldn't be more simple to install. Three lag bolts each right into the wall and we were good to go. Maybe need to bend a bit for square depending on your wall, etc. But easy peasy to do. Been up a couple seasons no sign of rust. Will probably outlast me.

Almost everything people say about these brackets is true: 1. They come as loose pieces with no assembly instructions, you WILL need the photo to properly put these together. 2. The holes for the u-bolts don’t quite line up, you’ll have to assemble each bracket loose in order to get the u-bolts in properly. 3. The flanges are not quite bent at the right angle, be prepared to use a vise or strong pliers to bend to suit. 4. All the screws/bolts/nuts are included, but you’ll want to buy either lock nuts or double nuts to make secure connections. You may also want to add washers/lock washers. Actually, there is an extra short lag screw that I’m not sure what the purpose is. One thing I don’t agree with is where some people think it’s not strong enough. It appears to be 12gage metal (slightly less than 1/8” thick). No, it might not hold a big dish antenna on a 10’ pole in a strong wind, but it will more than serve my purpose. It looks more electroplated rather than hot dipped galvanized, but it should stand up well to the elements. Generally pleased overall.

Truthfully I probably overloaded it. Originally I had this set up with a cell phone booster antenna. 10 foot of 1 1/2" mast holding up a 9oz antenna. The 2 brackets were only mounted about 20" away from each other. That worked fine. Then I added another 10' mast coupled to the other mast, this one was 1 1/4" and it supported a GMRS antenna which is about 5' tall and 2 1/2lbs. No problems during the summer even though there were windy days. Lots of trees around my area probably tempering the wind. Then winter came, the leaves fell off the trees and there was a day with some 35mph gusts and that bent the support. Mast was at about a 15º angle. I was able to bend it back up straight and then I reinforced the triangle portion to prevent it from bending again. Then weeks later more wind, 45mph gusts bent it again. This time the reinforcements held but the straight section after the triangle bent. Thee end. I got a more stout bracket, this one was not strong enough for my conditions.

To say that this unit is heavy duty is to waste everybody's time. The unit's main parts are made from 11 gauge plated steel, certainly not worth the paid price. What a disappointment. I'll return mine
