## Description

GEMEK Double shielded coaxial extension cable made of low loss S-LMR240 sized pure copper coax cable. Specifications: - Connector 1: SMA Male plug 50 ohm - Connector 2: N Male plug 50 ohm - Length: 3 feet(1 Meters) - Impedance: 50 Ohm - Coax: Double shielded Low-loss S-MR240 size (0.240 inch diameter) - Operating temperature : -40°C ~ +85°C. - Minimum coiling diameter is only 1.5 inches. - 90 degree bends in one inch or less without loss. S-MR-240： S-MR-240 is an excellent cable for runs up to 25-30 feet in WiFi and Cellular use, and provides superior performance for HF/VHF/UHF installation up to 150 feet. The PE jacket used on S-LMR-240 makes it tougher and able to stand abrasion. Thin, flexible, light-weight S-MR 240-sized coax makes installation easier, especially for tight bends. 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)

Review: Good quality and a good price. well fitting connectors. Take note that the cable is very rigid (due to the pure copper conductor) and not that flexible. I use it for a field meter and works good.
Review: Expensive
