Very thick and sturdy
I recently purchased this product to install an outdoor antenna for wireless data, and I couldn't be happier with my decision. The construction of the antenna is impressively sturdy, making it suitable for various weather conditions. The thickness of the materials used gives me confidence in its durability and performance. Since installation, it has worked like a champ, providing a strong and reliable connection. Overall, this has been a fantastic addition to my setup, enhancing my wireless data experience significantly.

Wow! This Cable Means Business
I purchased this cable to connect my Wilson 4G LTE directional antenna to my MOFI 4500 and WOW! This combo increased my down and up speeds by over 10Mbps! I am very impressed with the quality of this cable and you definitely get what you pay for as there are much cheaper cables out there but they won't hold signal anywhere near what this cable provides! It is costly but for solid 4G signal, well worth it! The only caveat, although necessary due to the quality of the cable, is it is rather difficult to work with since it is so thick.

I must have gotten a dud
Upon initially opening the cable, I was impressed with the quality and it returned good test results. Once I installed on my project though, I noticed one of the N connectors was sliding off, exposing the pin between the connector and coax. Allowing the coax to completely pull away from the connector with very little force. Luckily I noticed immediately and shut off my radio before any noticable damage could be done. I then inspected the other side of the cable and that connector came off with very little force as well. It seems the ends weren't crimped sufficiently and there was minimal friction holding them on. For some reason, I wasn't able to get the return process on Amazon to work for me, so I resorted to attempting to fix the cable myself. Luckily I had some 3:1 waterproof heat shrink in the right size. So I used that and installed it higher on the connector, up to the knurled collar. Allowing the glue to grab onto the connector and hold it on a little better. In the first photo, the left connector is already "repaired", the right side is how it came from the factory (Note that the heat shrink doesn't actually touch the connector). The second photo shows the connector fully removed (with very little effort). Since I don't have the right crimping tool, I wasn't able to do a whole lot about that, but I'm hoping this fix will work for my project. Judging by the other reviews, it seems my item may have been a rare slip through QC. Even though I had to do some repairs before using, I still feel like the coax and connectors are of high quality and worth the price. Just be sure to check the ends before installing in an outdoor environment.

This coax seem to be a similar type to LMR 400 Coax. Worked well for my project.
