Cavo antenna ALLNET LMR-195 SMA(m) a SMA(m) 500 cm

Coaxial antenna cable ALLNET LMR-195 SMA(m) to SMA(m) 500 cm is a 5-metre RF interconnect designed to link devices with SMA male interfaces. Constructed with LMR-195 type coaxial geometry, the cable provides a balance of low signal attenuation and mechanical flexibility for both indoor and sheltered outdoor routing. It is suitable where an extended SMA-to-SMA lead is required for routers, external antennas, cellular modems and RF test setups.

Advantages

The LMR-195 construction reduces insertion loss compared with thinner coax types while remaining flexible enough for neat installation in confined spaces. SMA male to SMA male terminations ensure a secure threaded connection compatible with standard SMA ports. The 5 metre length gives extended reach without intermediate adapters, and the cable jacket offers basic protection against abrasion and handling during deployment.

Suitable for

• Connecting routers, cellular modems and gateways to external antennas
• Extending antenna leads between antennas and RF equipment
• Temporary or permanent links in test benches and measurement setups
• Indoor or sheltered outdoor routing where a durable SMA-to-SMA lead is needed

Key specifications

• Cable type: LMR-195 coaxial
• Connector type: SMA male to SMA male (threaded)
• Length: 500 cm (5.0 m)
• Impedance: 50 ohm characteristic impedance
• Frequency range: suitable for typical RF applications up to several GHz
• Flexible jacket for routed installations

How to use

Attach the SMA male connectors to the corresponding SMA female ports on your devices, ensuring threads are engaged and hand-tightened to provide a secure electrical connection. Avoid over-tightening with tools to prevent damaging the connector bodies. Route the cable to minimise sharp bends and avoid kinks; maintain bend radii consistent with LMR-195 handling to preserve signal performance. For outdoor use, keep connectors and junctions protected from direct exposure to water and harsh weather.

Recommendations

For best performance, use the antenna cable for short- to medium-length RF runs where low loss and flexibility are required. Inspect connectors periodically for corrosion or mechanical wear, and replace the cable if the jacket is cut or the connectors show signs of damage. When higher environmental protection is needed, use additional sealing at the connector interfaces or mount the connection in a weatherproof enclosure.
