Solid J-Mount extender. Works well!
This mount is perfect for what I needed it for -- to mount the BoostWaves Antenna to the side of my roof. It is strong and can be easily manipulated into position and then tightened down. It is powder coated too so it will last forever without rusting. I needed more height than what this offered, so I went to my local hardware store and bought an 8-foot piece of 1" diameter PVC tube to use as an extender. Much cheaper than buying a metal extender here on Amazon and it will last just as long. I extended my antenna 6 more feet higher. I drilled holes into the top of the PVC tube and ran wire to all four corners of my roof to keep the pvc steady in the wind. No problem! Simply put the PVC into the top of this mount and bolt it in. Works like a charm and I definitely recommend this J-Mount. Just be careful it fits your antenna diameter. The maximum diameter to insert any pvc tube, extender tube or antenna tube into the top of this mount is 1 inch! Of course, you can buy a slightly smaller diameter, but DO NOT buy a larger diameter extender unless you have an adapter to scale it down to 1" or smaller.

Great for Meshtastic antenna
This sturdy mast has proven to be an excellent mounting solution for Meshtastic antennas. The powder-coated steel construction shows no signs of rust or degradation after months of outdoor exposure, and the 40-inch height provides good elevation for improved radio coverage. The pivoting base is particularly useful for Meshtastic installations, allowing you to fine-tune antenna orientation without remounting the entire assembly. While designed for TV antennas, the universal mounting hardware works perfectly with standard Meshtastic antenna brackets and adapters. The included mounting hardware is genuinely all-weather - proper stainless steel bolts and nuts rather than cheap plated alternatives that would rust. The pole diameter is compatible with most standard antenna mounts and U-bolts. Installation is straightforward, with pre-drilled holes in the base making it easy to secure to various surfaces. The pivot feature is particularly valuable during initial setup, as you can easily adjust the mast angle to optimize your Meshtastic node's coverage without having to remount everything. Once tightened, the pivot base remains rock-solid even in strong winds. One tip for Meshtastic users: consider adding some silicone sealant around the mounting holes if installing on a roof or exterior wall, and use a small section of pool noodle or similar foam at the pivot point to prevent water ingress. The mast itself is plenty strong for most Meshtastic antennas, but you might want additional guy-wire support if using heavier directional antennas or installing in very windy areas.

Good but not great.
These mounts work as expected. Not as heavy duty as I expected though. I decided to try and cut the cord. For years I had cable, and then I switched to directv. My directv bill averaged $98 per month and really all I watched were the ESPN’s and the network channels. I decided to cut the cord. I have AT&T Internet so WatchESPN streams on my Roku and AppleTV’s at home perfectly. I thought that if I could get the network channels then I could cancel Directv. The problem is, I am located about 50 miles from the broadcast tower and 2 of the 4 network channels are broadcast in VHF while the remaining channels are UHF. This would mean that I would need 2 antennas. So I went to antennasdirect.com and began researching. 2 websites that were a huge help were http://www.antennapoint.com and http://www.tvfool.com Both websites have data on the closest television towers at your address. They show the frequencies and the direction in relation to your home. Over the air (OTA) television is directional meaning you antenna must be aimed at the tower broadcasting the channels you plan to pick up. (Especially the further you are from the broadcast tower). I decided to order 2 antennas. UHF and VHF. VHF antenna (Clearstream 5 – I highly recommend. It works great): https://www.antennasdirect.com/store/vhf.html UHF antenna (DB8e – This antenna worked wonderfully as well): https://www.antennasdirect.com/store/DB8e-Ultra-Long-Range-Outdoor-DTV-Antenna.html The clearstream came with a VHF/UHF antenna combiner. So I used the combiner to combine the two antennas. A combiner is nothing more than a splitter used backwards from what I could gather. I intended on splitting my signal to 4 different televisions. Everything I read said that when you run long runs of coax cable, the television signal is diminished drastically. So, I purchased a pre-amp and a powered 4-way splitter. Pre-Amp: http://www.amazon.com/Winegard-LNA-200-Boost-Digital-Preamplifier/dp/B00DQN3R9O/ref=pd_sim_e_3?ie=UTF8&refRID=0NDCZXJGZZ8ZK1PEMR6P 4-way splitter: http://www.amazon.com/Antennas-Direct-CDA4-Distribution-Amplifier/dp/B0082ZJNW6/ref=pd_sim_e_6?ie=UTF8&refRID=0NDCZXJGZZ8ZK1PEMR6P I decided I would install my antennas in the attic. I felt like I would get more life out of the cables, antennas, and splitters if they were out of the elements. I wasn’t sure if the signal strength would be strong enough but I thought I would try it, and if it didn’t work then I could mount onto the roof. I installed the antennas in the attic and hoped I wouldn’t need the pre-amp or the powered splitter. The first thing I did was hook up a regular 4-way splitter and ran a channel search. All the desired channels came in, but the signal strength was too low and there was a lot of buffering. I decided to hook up the powered 4-way splitter and that increased the signal strength a bunch but still it was in the 65-70% range and that was not what I wanted. I then hooked up the pre-amp and boom! I had a 90% or more signal strength on all channels. I also made sure to use only RG6 coax cable and cut the cables to be as short as possible. Here are the RG6 cable tools I purchased. Cutter and stripper: http://www.amazon.com/dp/B0099DIV4G/ref=sr_ph?ie=UTF8&qid=1420732747&sr=1&keywords=RG6+cable+tools Cable end compression tool: http://www.amazon.com/RG59-Connector-Waterproof-Connectors-Crimping/dp/B0050N0S36/ref=sr_1_8?ie=UTF8&qid=1420732747&sr=8-8&keywords=RG6+cable+tools Cable ends: http://www.amazon.com/PCT-TRS-6-Universal-Coaxial-Compression-Connector/dp/B00760VRCM/ref=pd_bxgy_hi_img_y I also used two mounts in the attic. They worked great. Here is the link: http://www.amazon.com/gp/product/B000WOVD1Y/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 That’s it…that is all you need to get free OTA television. I was able to receive all the channels available in my market. WMAB 2/WMAE 12 (x.1 PBS/MPB, x.2 PBS HD, x.3 Create) WCBI (4.1 CBS, 4.2 MNTV, 4.3 The CW) W07BN-D (IND/TBN) WTVA (9.1 NBC, 9.2 ABC) W25AD (TBN) WLOV (27.1 Fox, 27.2 Me-TV, 27.3 This TV) W34DV/W39CA (UBN) WEPH (49.1 CTN) The best part of all this, was calling Directv and canceling my service.

Nice sturdy mount for antennas
This mount is plenty tough. I had originally wanted one a little narrower but I do like the strength of this one and it worked well.

Fantastic mount
You cannot get a better deal on mounts. Heavy duty, Sturdy! However the adjustment can be tough if you want to install the mast at an angle. Suggest you take a four foot level and a one foot cardboard square and use the level to mark vertical on the cardboard at the mounting location. Then take the cardboard and align the mast with the vertical line drew on the cardboard on a flat work surface. Mounting will go a lot easier.

Antenna catches with stand
I put my antenna on this stand and on the back porch and it picks 176 channels including ABC,NBC,CBS and even FOX. FOX I could not catch without this stand.

I'm on the verge of swearing by these mounts
Yep. Nice mounts. Easy to assemble and solid construction. I have two of these mounts I use for professional weather station sensors. We don't get many hurricanes up here in north Alabama, but if we did, I'm confident my weather data would press on using these mounts.
