Coaxial Cable HiSmart TV990801 LMR-400, 7m, N-male to N-female

HiSmart TV990801 is a 7 m coaxial cable built to the LMR-400 specification, fitted with an N-male connector on one end and an N-female connector on the other. Designed for RF signal transmission, this cable provides low loss and durable performance for indoor and outdoor antenna, router or radio installations. The cable has 50 ohm impedance, a black UV-protected jacket for outdoor use and an operating temperature range from -40°C to +85°C.

Advantages

The LMR-400 construction ensures low attenuation and consistent impedance for reliable RF performance over the 7 m length. Connectors are N-male to N-female for straightforward mating with standard antenna and radio equipment. The cable jacket offers UV protection for outdoor deployment and the specified temperature range supports a wide variety of installation environments. HiSmart TV990801 is compatible with LoRa, LoRaWAN and Helium networks where low-loss cabling is required.

Suitable for

• Connecting outdoor or indoor antennas to routers, modems or gateways
• LoRa/LoRaWAN and Helium gateway and node installations
• Medium-distance RF runs where low-loss 50 Ω cabling is needed

How to use

Verify that both mating devices use N-type connectors and that the connector gender matches the intended ports. Route the cable avoiding sharp bends or kinks and secure it with appropriate clamps or cable ties, keeping some slack to prevent stress on connectors. For outdoor runs, ensure connectors and any exposed joints are weatherproofed with appropriate sealing tape or boots. After connection, check signal levels and tighten connectors by hand and then with the proper torque tool if available to ensure a reliable RF connection.

Usage recommendations

For best performance, avoid tight bending radii and minimize connector adapters. When used outdoors, maintain UV-exposed cable runs and seal connector interfaces to prevent water ingress. Regularly inspect the cable and connectors and replace if the jacket or connector integrity is compromised.
