Using this for a 2 meter ham radio application. Running from my roof to my basement and didn't want a poor SWR due to mediocre cable. Easy to work with and jacket and shielding are well made.

This coax is acceptable. But it does not perform as well as times microwave LMR 400 up in the 440 band UHF and higher. But it seems good for HF/VHF with minimal loss. It doesn’t meet ALL the specs that they give though and I have tried multiple pieces with my test equipment and have found it to not meet there specs, especially in the UHF band when I do a sweep test. But like I said, it is acceptable for HF and VHF, it is just as good as RG 213 or LMR 400 in that frequency range. Most ham radio guys do not buy their coax from Amazon, so it will work perfectly fine for the guys on CB radio that do shop on here. I was just checking out to see if there are any bargains available.

This coax seems to have decent build quality. The shield/braid is a lot thinner than LMR400--I don't have the equipment to test/verify the loss compared to LMR400. Installed 100' on a 2m/70cm dual-band amateur radio antenna, and it seems to perform decently. We'll see how it holds up to the sun and weather, but i'm confident it will hold up ok.

Much more flexible than LMR-400. Is it the same quality TX/RX as the expensive stuff? I have no idea. But I know it's gotta be better than the bottom shelf stuff most Hams grab first and a lot easier to roll out and run than the even better stuff. Unless I start getting bad signal reports, this stuff will do great.

The KMR400 coax has the same specifications as the Times Microwave standard LMR400 cable but at about 1/3 the price. This cable is constructed similarly to the LMR400 and is similarly a very stiff cable. The cable is not like the Times Microwave UltraFlex version which is much more flexible and has a slightly larger power loss.The connectors solder easily to the KMR cable, but the outer shield wire seems frizzier the LMR. I measured the coax cable loss with a MFJ 259 analyzer and verified the loss was the same as specified which is the same as the LMR.I use this cable for all feedlines outside my ham radio shack. Inside, I use the LMR400 UltraFlex cable. For portable antennas, shorter feedlines and lower frequencies I use the MOOKEERF coax found on Amazon. The MOOKEERF cable is smaller, has more loss and is cheaper.
