## Description

GEMEK Double shielded coaxial extension cable made of low loss S-MR240 sized pure copper coax cable. Specifications: - Connector 1: SMA Male plug 50 ohm - Connector 2: N Male plug 50 ohm - Length: 25 feet(8 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-MR-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)

*by M***N on September 29, 2019*

I purchased two of these cables for two Watson antennas. Both cables came with the correct end connector. After running the wires from my outside antennas up into my attic and into my house I was pleased that both cables not only functioned great but we’re durable and easy to work with. I would recommend these cables. Lastly, the cables transmitted my LTE signal beyond my expectations, although the mofi router was the driving force.
