This KMR400 RF Coaxial Cable low loss transmission line can be used in almost any application where handling characteristics and when improved Shield and low loss is required.Specification： 3GHZ VSWR≤ 1.1 6GHZ VSWR≤ 1.15 3GHZ Attenuation≤-0.04dB/FT 6GHZ Attenuation≤-0.06dB/FT Characteristic Impedance: 50ohm Min. Bend Radius(Install): 2in Max.Operating Frequency: 6000MHz Operating Temp: -40 to +80℃ Maximum tensile strength: 21.3Ib Peak Power: 16.0 kWPackage Include： 1 x 100ft LMR400 Coaxial Cable

Review: As close to LMR400 as you're going to get, at less than half the price. I terminated the supplied 100' cable with crimped N types, and hooked it up to a calibrated 8714ES. Losses at some selected frequencies for the 100' supplied: 7.3MHz -0.35dB 14.3MHz -0.61dB 28.3MHz -0.95dB 51.3MHz -1.14dB 70.3MHz -1.26dB 145.3MHz -1.68dB 221.3MHz -2.01dB 435.3MHz -2.88dB 1296.2MHz -5.13dB 1420.2MHz -5.40dB 1575.1MHz -5.72dB 2400.1MHz -7.07dB
Review: Works fine, just what I expected in terms of quality and functionality. Used this exclusively for a new tower installation with four antennas.

### ⭐⭐⭐⭐⭐ Review
*by J***T on 23 September 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.
