## Description

KMR240 SMA Male to SMA Male Coaxial Cable 50 ohm Coax Ultra Low Loss Antenna Extension for 3G/4G/5G/LTE Network Equipment, GPS, RF Radio (6FT)

## Features

- [Specification]-Connector: SMA male to SMA male(NO RP-SMA), imdepence: 50 ohm, Cable type: KMR240.
- [Ultra Low Loss]-The KMR240 jumper cable is bigger than RG58 cable, so it could transmit data with lower signal attenuation that low to -2.65db(25ft,1800MHz) and keep VSWR≤1.15.
- [Firm Connected]-We fix the connector with 2.2" adhesive tube and it will not easy to fall off from the cable. And that can provide a heavy duty and firmly connection, really durable and professional coaxial cable.
- [High Grade Material]-This KMR240 SMA cable inner conductor is made by pure copper and build with tinned copper braid, that can make sure the signal transmission efficiently and stable. The PVC jacket is waterproof and has strong oxidation resistance, and can be adapted to outdoor for a long time
- [Widely Application]-Compatible with all SMA-based equipment, including splitter, antenna, modem, RF radio, GPS, and 3G/4G/LTE Network system etc.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great for UHF and higher frequencies
*by T***A on January 23, 2025*

Tested well with a NanoVNA. It also has the right connectors for solid SMA connections and definitely seemed to improve reception at 1090MHz (for ADS-B) vs cheaper RG-58 coax (which has higher losses at that frequency) where I also had to use PL-259-to-SMA adapters (also causes some loss). Order the length you need, to allow the antenna to be higher, but not too long where again losses would increase.

### ⭐⭐⭐⭐⭐ Great for SDR
*by L***E on January 7, 2025*

I used these to hook up an SDR Play, and they worked well with low insertion loss and are pretty flexible.

### ⭐⭐⭐⭐⭐ It does cable things
*by D***P on October 4, 2024*

Solid, sturdy, works well, carries signal and dc power. I did add a ferrite bead to help with noise, but I also added some to other components so not sure if it had to do with this cable, but hey maybe you should think about getting some ferrite beads.
