## Description

SMA Male to N Male cable made of low loss LMR 240 sized coax cable.SMA to N Male coax cables are used to connect SMA radio sources such as modem, routers, etc. to the female N connector found on many external fixed mount antennas (e.g. Yagi, LPDA, directional panel, sector, omni-directional). N to SMA coax cable can also be used for connecting lightning arresters, meters, or signal boosters  Thin, flexible, light-weight 240-sized coax makes installation easier, especially for tight bends. Specifications Connector 1: SMA Male plug 50 ohm Connector 2: N Male plug 50 ohm Length: 25 feet Coax: Low-loss LMR-240 size (0.240 inch diameter) Impedance: 50 ohm NOT for use with Wi-Fi (RP-SMA) or video (cable/satellite/CATV) devicesProxicast's coax extension cable assemblies are constructed with top quality extremely low-loss cable and gold plated connectors. Each cable assembly is fully tested. Proxicast recommends LMR195 coax for assemblies up to 10 ft, LMR240 for lengths up to 25ft and LMR400 for lengths up to 75 ft.RF ConnectorsSMA Female jacks are commonly used on 3G/4G/LTE cellular modems, routers and signal amplifiers - check with your equipment manufacturer. Many indoor cellular antennas have SMA Male connectors; most outdoor antennas have either N-Male or N-Female connectors.RP-SMA (Reverse Polarity) connectors are commonly used on Wi-Fi equipment. SMA and RP-SMA connectors will not mate.Video equipment (cable, satellite, TV, etc) uses "F" connectors - which look similar to SMA but they will not mate with SMA connectors.See the photo gallery above for pictures of the exact connectors on this coax extension cable and note the gender of the connectors you need to ensure male-to-female mating.All outdoor connections should be weather-proofed to minimize moisture in the cabling. Use our Self-Bonding silicone tape for fast and easy connection sealing.
