## Long description

HiSmart TV990757 is a 0.5 m coaxial cable built with LMR-400 transmission line and fitted with N-male to N-female connectors. It is developed for RF and antenna connections, providing a short, low-loss link between devices with N-type ports. The cable is suitable for both indoor and outdoor use and includes UV protection for outdoor installations.
Advantages
The LMR-400 construction ensures low attenuation and reliable signal transmission over the short 0.5 m length. With a 50 ohm impedance and durable black jacket rated for -40°C to +85°C, the cable is resistant to typical environmental conditions. The N-male to N-female connector pair offers a secure, industry-standard connection compatible with LoRa, LoRaWAN and Helium antenna systems.
Suitable for
Connecting LoRa/LoRaWAN and Helium antennas to gateways or radios
Short RF jumper between N-type ports in test setups
Base station feeder or antenna extension where a durable N-to-N connection is required
Key specifications
Cable type: LMR-400
Length: 0.5 m
Connector 1: N-male
Connector 2: N-female
Impedance: 50 ohm
Operating temperature: -40°C to +85°C
Color: black
How to use
Ensure both devices have compatible N-type ports. Align the N-male connector with the N-female port and tighten by hand or with an appropriate torque wrench to the connector manufacturer's recommended torque. Route the cable to avoid sharp bends; maintain a gentle bend radius to preserve performance. For outdoor installations, use additional sealing or weatherproofing at the connector interface if exposure to persistent moisture is expected.
Usage recommendations
Use the cable for short-distance RF connections where low loss and robust N-type connections are required. Avoid excessive bending, pulling on the connectors, or exposure to chemicals that could degrade the jacket. If used outdoors long-term, check connector seals periodically and reapply weatherproofing when necessary.
