The short length reduces signal loss and the robust connectors provide secure mechanical and electrical contact for reliable performance.

## Long description

HiSmart TV990665 is a 0.5 m coaxial cable of LMR-400 type with an N-female connector on one end and an RP‑SMA‑male connector on the other. It is designed for RF signal transmission and is suitable for connecting antennas, routers and radio equipment that require these terminations. The LMR‑400 construction offers low attenuation and durable performance for outdoor use, and the short 0.5 m length minimises additional signal loss.
Advantages
The LMR-400 coaxial construction provides low attenuation and stable RF performance. Robust N-female and RP‑SMA‑male connectors ensure secure mechanical and electrical contact. The cable is UV-protected for outdoor installation and rated for a wide operating temperature range from -40 °C to +85 °C. The 50 ohm impedance matches common RF equipment specifications.
Suitable for (tasks / use cases)
 Connecting LoRa/LoRaWAN and Helium antennas to gateways or radio modules
 Linking external antennas to routers and access points with RP‑SMA ports
 Short RF jumper connections in test setups and installations
Key specifications
 Cable type: LMR-400
 Length: 0.5 m
 Connector 1: N-female
 Connector 2: RP‑SMA‑male
 Impedance: 50 ohm
 Operating temperature: -40 °C to +85 °C
 Color: black
How to use
Connect the N-female end to the corresponding N-male port on the antenna or mast-mounted equipment and attach the RP‑SMA‑male end to the RP‑SMA connector on the gateway, router or radio device. Ensure connectors are hand-tightened and avoid over-torquing. Route the cable to minimise sharp bends and secure it with cable ties or clamps at intervals to prevent strain on the connectors.
Usage recommendations
For outdoor installations, verify that both mating connectors and any exposed junctions are weather-sealed. Keep the cable as short as practical to reduce loss; use 0.5 m for short jumper links and consider longer LMR-400 lengths only when necessary. Avoid repeated flexing at the connector ends to maintain long-term electrical contact.
