## Customer Reviews

### ⭐⭐⭐⭐⭐ Excellent coax for amateur radio antennas
*by J***T on November 26, 2023*

I have installed this to my HF radio antennas and am very happy with its construction, handling, and performance. The center conductor is copper-clad aluminum and so it is a bit lighter in mass than that with pure copper center conductors, and is still a substantial and low loss cable for use at HF frequencies. While the product photo shows a wooden spool, that is not included in the order. What one will get is a nicely wound length of coax for termination by the user. I used crimp-on fittings and am very pleased with this coax cable. No problems or issues at all - it is a drop-in replacement for LMR-400 and RG-8 coax. Recommended! Great value for its price.

### ⭐⭐⭐⭐⭐ Ran it from my office to my attic
*by S***N on December 12, 2022*

I ran it from my office, inside an interior wall cavity that did not have any any other cables/wires in it. It runs from about 1 foot off my main floor's floor (at the height of a normal outlet), through the second story floor, and into the attic space where it goes at a diagonal towards the highest peak of the roof, there's still a bit of slack, although not a huge amount to spare.I connected it to the VHF/UHF J-Pole antenna that is mounted to a support post that leads to the peak of my roof line. I've seen no measurable difference on my SWR meter between having a shorter 10ft cable that I tested the Jpole with while building it as compared to the 50ft of this cable. If anything, I've actually seen better SWR because nothing is near the antenna to potentially screwing up the radiation pattern.

### ⭐⭐⭐⭐⭐ Great value at lower price
*by J***T on September 23, 2022*

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.
