## Overview

The GEMEK 3ft SMA Male to N Male cable is a professional-grade, low-loss coaxial extension crafted from pure copper with double shielding and gold-plated connectors. Designed for 50Ω impedance, it supports a wide range of high-frequency applications including 3G through 6G, LTE, WiFi, and RF radio setups. Its flexible yet durable S-MR240 coaxial design allows tight bends without signal loss, making it ideal for both indoor and outdoor antenna connections. Compatible with leading network equipment brands, this cable ensures superior signal retention and long-term reliability for demanding wireless communication needs.

## 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: 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-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)

Review: Perfect for my application. No signal lost, good quality!
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.
