Coaxial cable HiSmart TV990764 LMR-400, 1 m, N-male to N-female

HiSmart TV990764 is a 1 m LMR-400 coaxial cable assembly with N-male to N-female connectors designed for reliable low-loss RF connections. The cable is suitable for antennas, routers, modems and other radio frequency equipment with N-type interfaces, and is constructed for indoor and outdoor patching where a flexible, durable coax with UV protection is required.

Advantages

The LMR-400 construction delivers ultra-low attenuation and stable signal transmission over the 1 m length while maintaining flexibility for tight routing. Standard N-type connectors provide secure, threaded mating and consistent impedance matching. The assembly is made for outdoor use with UV-resistant jacket material and a temperature range that supports operation in cold and hot environments.

Suitable for

• Connecting external antennas to routers, gateways and modems with N-type interfaces
• LoRa, LoRaWAN and Helium network installations requiring low-loss coax
• Indoor and outdoor RF patching where a robust, weather-resistant cable is needed
• Test and measurement setups that require a 1 m interconnect with N-male to N-female

How to use

Ensure both mating connector threads are clean and free of debris. Hand-start the N-male into the N-female, then tighten by hand until snug; use a torque wrench or appropriate tool if the installation requires specified torque. Route the cable to avoid sharp bends that could exceed the LMR-400 minimum bend radius, and secure it with suitable clamps or ties to prevent strain at the connections. Observe the operating temperature limits and avoid prolonged exposure to direct heat sources.

Usage recommendations

For best RF performance, keep the cable run as short as practical, avoid kinking or compressing the jacket, and verify connections periodically for corrosion or looseness in outdoor installations.
