## Description

GEMEK Double shielded coaxial extension cable made of low loss S-MR400 sized pure copper coax cable. Specifications: - Connector 1: SMA Male plug 50 ohm - Connector 2: N Male plug 50 ohm - Length: 50 feet(16 Meters) - Impedance: 50 Ohm  - Coax: Double shielded Low-loss S-MR400 size (10.3mm/0.4 inch diameter) - Operating temperature : -20°C ~ +70°C.  - Minimum bending radius is only 2.44 inches. - 90 degree bends in one inch or less without loss. S-MR-400： S-MR400 is an excellent cable for runs up to 50-70 feet in WiFi and Cellular use, and provides superior performance for HF/VHF/UHF installation up to 250 feet.S-MR400 Coax is the same size as RG-8U or RG-213 cable, 0.405 inches in diameter. A larger cable means a much larger center conductor and supports better signal retention for higher frequency use. S-MR400 assemblies are a drop-in replacement for RG-8/9913 Air-Dielectric type Cable and are ideal for Jumper Assemblies in Wireless Communications Systems, Short Antenna Feeder runs, and any application requiring an easily routed, low loss RF cable.Application:  Use to connect SMA radio sources such as modem, routers, WiFi Signal Booster Repeater, etc. to the female N connector found on many external fixed mount antennas (e.g. fiberglass omni-directional, directional panel, sector), receivers, meters and radio transmitters.  NOTICE : NOT for use with video (cable/CATV/satellite) devices Package List: 1 x N Male to SMA Male Low Loss Coaxial Cable (As the Picture Shown)

## Features

- ✔Connector: All-copper SMA Male to N Male adapter (Note: Not RP-SMA Cable, Not F Male Cable).
