This antenna mount is easy to install and is very stable and secure. No drilling required. all you need is wire cutters and an 11mm wrench (socket wrench will not work unless it is a very deep socket). I have a 6 foot pole mounted to mine and it is rock solid. While it can be done with one person I would suggest you get a friend to help. Two of us completed the install onto the chimney in under 20 minutes. The documentation is completely useless. As others have suggested it helps a lot to get as much of the slack out of the cables as possible before you tighten the tensioning bolts. Quick 10 step instructions:
1. Loosen the nut holding both halves of the bracket together but don't remove the bolt.
2. insert the U-Shaped bolt as shown in the product picture. Attach the lock washer and nuts but don't tighten them.
3. insert the tensioner (the thing with the triangular head). thread on a lock washer and nut but leave it near the end of the tensioner.
4. Starting with one end of the strap ... feed the strap through one of the 4 flat belt keepers, then through the tensioner (triangle head thing) then back through the belt keeper. You can fold the belt where it goes through the tensioner. and make this side look neat.
5. position the mount where you want it on the chimney and wrap the cable around the chimney then repeat step 4 but don't fold the belt.
6. this is the important part. Take up all the slack in the belt before folding it at the tensioner.
7. At this point the mount should already feel stable. now tighten the nuts on the tensioners.
8. Repeat for the second mount.
9. Insert the antenna pole.
10 Tighten the remaining nuts (three on each mount) and you are all good.
The instructions are helpful, but the additional input from Amazon reviewers was also useful.
I was able to install by myself, but I'm mechanically inclined and I have good access to my chimney. A second person would definitely make for an easier/quicker installation. You need to be comfortable/able to sling the straps around (or over) the chimney, and hold them in place, and secure the fasteners. The input from another review (install one strap clamp completely, and leave the other clamp loose) was critical. I recommend this product for a mast/post that is LESS THAN 1.5 inches diameter.
The materials are a mix of stainless, galvanized and anodized. I covered some of the fasteners/anchors with aluminum flashing tape to provide additional weather protection.
It has been in place for 6 months and is holding up well. I recommend semi-annual inspections to check the fastener tightness.
Some notes about my specific installation, some directly and undirectly related to the product - My TV sattelite mount is unconventional and required a bit of "engineering" on my part to complete the installation to my satisfaction. The satellite mount is NOT circular (it is ovalized) and it required the largest post/mast that this product would accommodate. I purchased a piece of EMT (galvanized electrical conduit, 1-1/2" inside diameter, I think) and had to rip pieces of EMT to shim the satellite bracket in place. The EMT has an outside diameter of 1.75", and this is was a bit larger than the brackets took a bit of effort to "Snap" into each receiver/clamp. You can see that the outer screws of each clamp are slightly bent due to the larger diameter of the EMT.
I used this mount on the side of my two story house up toward the peak to mount a 10ft mast (two 5ft sections) to put my new weather station above the roof of my house. There are no instructions as other stated. And those folks are correct that the bottom support bar is too short to mount in the middle hole as the picture on Amazon shows it. It works great if you mount that bottom support rod in the first hole (one of the two bolts that hold the other two sections together). However, then you need to add a couple washers on the second bolt to even out that middle otherwise you will tilt the mast ends in together too much. Adding the washers on the second bolt and putting the support bar on the first bolt everything lines up level with the wall. The holes are 16in apart on the left to right of both the top and bottom mount sets. And if done as I just stated, then the bottom hole for the support bar was 18.5in below the center of the two other holes. Worked out great. It holds my 10ft of mast very sturdy and in the future I can loosen the mounting nuts/bolts at the end where the masts are to lower the mast down and bring the weather station down to me (on a ladder) for battery change once per year or so, then push the mast back up and tighten back down the nuts on the bolts.
Although it seems to be obvious how the Y-wall mount will go together there were no instructions, i.e. owners manual supplied with the device. Whoever manufactured the the mount was, to this purchaser, not proud of his product as there was no name of the manufacturer on the carton or on the product itself. In spite of all that, it looks simple to put together and reasonably well made. I haven't put the device on the back of my garage yet, but I'll let you know how it works. OBTW, the mounting holes appear to be 16" apart which, as most of you folks know, is the spacing for the building construction studs most of the time, in the US which is great!
Throw away the instructions and this set is perfect. I suggest pulling the straps through and then double back so that when you begin to tighten, it will pull the straps tight.
Easy to use. Instructions fairly clear. I did have to re do the clamp once as it slipped the first time I tried.
A tip: keep the clamp as close to the eye bolt as you can.
Product is competitively priced from this seller. But over all it's an expensive piece of stamped steel.
Saved me from drilling holes in my brick chimney tho.
I used 1" aluminum tube for my mast and the clamps held it tight.
Seems to be withstanding the high winds here
