LMR 400-75 Cable
The LMR 400-75 cable is built for outdoor exposure and flexibility. It features a bare copper inner conductor and an aluminum tape outer conductor, which enables the tightest bend radius of any cable of similar size and performance. It also has a foam PE dielectric, a tinned copper braid, and a black PE jacket. This cable is also UV resistant. The LMR 400-75 uses standard LMR 400 connectors including type-N and type-F male plug with a 75-ohm interface. View LMR 400-75 Connectors here.
LMR-400-75 connectors from Times Microwave are for 75 ohm LMR-400-75 Cable. Interface types include BNC Male, F Male and N Male. Most LMR-400-75 coax connectors feature crimp outer and non-solder center contact attach. Choose from solder-on, solder or spring finger center pins.
