Looks good

I ordered this for a low-loss solution for a mesh LoRa device. I wanted an antenna that could go in the attic, but I didn't want to put the device itself up there due to temperature swings throughout the year. Ideally you want the device as close to the antenna as possible with these extremely low wattage devices, but when that's not possible, you want a good low-loss cable, as short as possible.I terminated a 15ft length myself with the appropriate crimp connectors and put the device on the floor just below the attic. The antenna and cable came back at 1.15:1 SWR on my NanoVNA! This cable is amazing, and WAY cheaper than the LMR variant.I'm REALLY happy with this stuff!!

This KMR-400 is a decent quality 50-ohm coaxial cable, similar to a major manufacturer’s LMR-400 cable. The aluminum braid shield provides about 95% coverage, as advertised. The secondary aluminum foil shield appears to be of a thickness similar to LMR-400 cable. The foam dielectric is dense enough that it doesn't deform when applying connectors.I used this cable as a feedline for a half-wave dipole antenna, replacing a feedline that had been chewed on by animals. I easily applied quality UHF connectors of a crimp design to both ends of the cable for attachment to my antenna and ham radio. After testing in the HF band, the SWR reading was good and comparable to the cable it replaced.Overall, this is a good quality cable that I would buy for the right application. However, one drawback of KMR-400 cable, compared to LMR-400, is that it has a PVC jacket rather than a PE jacket, which would be more resistant to sunlight and burial over time. If either of those factors isn't critical, then this cable is a great value compared to the more expensive LMR-400.

Packed well. Ordered 100ft. Received 100ft. Installed N-type connectors on both ends and measured loss of 100ft using a Siglent SSA3032X spectrum analyzer. The cable exceeds LMR-400 specs out to 2.5GHz, which is near the limit of the SpecAn.The only complaint that I have is that peeling the foil from the dielectric was a little more difficult that I remember with Times Microwave LMR-400. It seemed fused to the dialectric.

100/100A great "LMR 400" analogue for use with a CB or HAM HF radio set up. Personally, this is the coax I'm using to run from the window pass through to the antenna for my CB/10M set up. It easily handles the power of the 10M radio and the CB is much lower power. It's low loss means more signal/power gets to the antenna. According to my analyzer, it's a fine piece of cable for the HF frequencies I'm using it at. (10M/11M)Ultimately, is it worth the price? Absolutely!

I had plans during the winter to stand up an all-band wire antenna, but alas it has yet to happen. This cable seemed fit for the job. What I can tell you is that I was at least able to do a basic continuity test with a multi-meter and everything was coming up roses. It was a perfect connection through and through without any crossover. The cable itself looks and feels like good quality to me and flexible enough for the job, although I admit I'm a bit of a newbie in the ham radio hobby.But all the boxes so far are checked as far as I'm concerned. I'll come back and share here if I encounter any issues in the process when actually putting it to use.

The jacket is a little shiny, and a little plasticy. Not the most bendable stuff out there, but alright for an install. Came fairly tightly coiled so could use to relax out a little. Didn't observe any nicks or other damage.
