Channel Master Universal Antenna Mount - Sturdy Steel Adjustable Mount for Secure TV Antenna Installation, 1.5" Pole Diameter, Extends from 24"- 44", Weather-Resistant, 7" Wall Clearance

I mounted a multi-band antenna with ground plane radials with this mount and it fits my roof line and equipment perfectly. Just tall enough to put the antenna above my roof without being too big. once installed it does not wiggle at all and there is a high degree of adjustability so you can get your antenna level regardless of how the base is mounted. The finish is very sturdy as well. I live in a saltwater environment and after several months, storms and blazing hot weather, this thing still looks brand new with no issues.

Very sturdy and lots of options for just about any angle. The pipe fits Starlink like a glove although I did cut about 8 inches off of it because I didn't need the extra height. I used an 1.5 inch muffler clamp to tighten the Starlink into the mount.

At first I was worried that the slant was not enough for my roof installation but there was just enough adjustment for it to fit. The directions showed a somewhat different view with the fixed screw at a different location than that of the mount but it worked. The CM-3090 J-Mount is very sturdy. Installation took me awhile but that is only because of using a long ladder to access the eave of the roof on my house. I drilled pilot holes to attach the base to the house. Overall I am very pleased and happy to find this J-mount from Channel Master. All the products I have ordered from Channel Master are excellent quality. I ordered the antenna installation kit to complete my installation and those products are also top-notch.

Overall this works well and serves it's purpose. The directions are a little confusing and I ended up having to remove some of the bolts a couple times to start over. At the beginning of the directions it is not clear which bolts should be used for each step. Also, I bought this so I could mount it on my roof eave at 45-degrees. Unfortunately it only seemed to mount at a maximum of about 30-degrees based on the rotation of the arm, so I had to improvise a little.

I have bought 6 of these mounts and will get many for each of my Antennas I have to deploy. Adjusts left and right and forward and backwards. Also works on eves that are not 90 degrees, like on my house I needed almost 180 degrees to get the antenna vertical and this mount did the trick. Get one, you won't be disappointed.

I purchased this specifically to use to mount my weather station on the peak of my pole barn. It was extremely easy to mount the bracket to the barn and equally easy to put the weather station on it and then get up the ladder and but the pole on the bracket. Three screw attach the pole to the bracket and it is easily adjustable. The steel is decent thickness and strong enough to hold up to a 70 mph wind gust that I recorded off the weather station just a few days after installing it at the first of November. The paint appears to be of good quality - it did not scratch during installation and before I wrote this review, I got out the extension ladder and climbed up to it and inspected it. It has been in use almost 8 weeks and is holding up as good as new. Although I did not use it for a TV antenna, I feel that it would hold up well with any light object, such as an antenna or a weather station. Highly recommend this if you are looking at it and comparing to other mounts. I did spend several days comparing and chose this one - I am very happy with my decision.

Came with clear instructions and and mounting hardware. You need your own tools. Those are not included. A #2 Phillips screwdriver and a socket or wrench (I think it was 1/2 inch, if I remember right—don’t quote me). One-man job. I installed it on my roof by myself. Pole extends 4 feet with predrilled holes. Happy with it. Would buy it again. Channel Master is high quality and has been in the TV antenna business since the dawn of the TV age in the 1950’s.

I bought this to mount a BloomSky weather station to. If you are considering the same, the BloomSky’s bracket u-bolts are just barely big enough to get around after taking off the rubber bolt covers. The lag bolts included are kind of cheap and I broke the head off one while using a driver to screw it in. So I drilled pilot holes and used a socket wrench on the others. Other than that, it seems pretty sturdy. It is steel and I have a small level with a magnetic side that came in handy to get it right. Channel Master sells this for forty bucks on their site plus shipping. Watch for the price swings. I paid fifty here with prime, then saw it nearly half price less than a month later. Amazon CS told me to pound sand, I’m SOL, when I asked about the price difference.

This product is easy to install with the included instructions. My only suggestion is to put some flat washers on the Lag Bolts because the head of the bolt is just larger than the holes.

I have the Televes Outdoor DAT Boss Mix UHF/VHF HDTV Antenna installed onto that antenna mast pole. It’s perfect. We had 100 kms per hour winds two weeks ago. Everything stayed straight.

I really like these antenna masts and have used many of them for a variety of applications ranging from mounting cameras and wireless bridges to Starlink dishes. The design is mostly well thought out, the materials are good quality and the assembly provides a lot of flexibility to suit most mounting locations and surfaces. The one problem I've had is the quality of the nuts and bolts that are provided with the assembly, the quality is poor and I've had a few bolt heads snap off. I now keep a stock of my own high quality, machined carriage bolts and never have a problem. I have also replaced the mechanism for securing the extension pole because the existing fastening solution is not reliable and damages/crushes the extension pole. With a few tweeks I consider this a good product in a market segment with a lot of garbage products.

Easy to assemble and insysll

The product is excellent, great buy!
