## Summary description

Short coaxial cable by ALLNET, model ANT-CAB-RSMA-RSMA-40-W, 0.4 m long with RP-SMA connectors on both ends. Designed to connect RP-SMA equipped antennas, routers or radio modules where a brief link is required. Flexible, compact cable suitable for tight installations and indoor use, providing straightforward signal connection.

## Long description

Short coaxial cable ALLNET ANT-CAB-RSMA-RSMA-40-W 0.4 m RP-SMA to RP-SMA Black is a compact RF interconnect designed for short-distance connections between devices with RP-SMA female ports. The cable measures 0.4 meters and features RP-SMA male connectors with reverse polarity on both ends, enabling a straightforward link between antennas, routers, wireless modules or test equipment where a brief, flexible connection is required. Its small diameter and pliable jacket make it easy to route in confined spaces and indoor installations.
Advantages
The cable offers reliable signal transmission for short runs while minimizing space usage and connector strain. Its RP-SMA to RP-SMA termination ensures compatibility with devices that use reverse-polarity SMA connectors, preventing the need for adapters in supported setups. The flexible construction allows gentle bends without kinking, and the 0.4 m length reduces excess cable that could degrade signal integrity in compact installations.
Suitable for
Connecting external antennas to routers, access points or cellular gateways with RP-SMA ports
Linking wireless modules, radio transceivers or IoT devices in test and development setups
Creating short jumper connections inside equipment racks or enclosures
Temporary or permanent indoor antenna extensions where a short, neat cable run is needed
Key specifications
Cable length: 0.4 m
Connector type: RP-SMA male to RP-SMA male (reverse polarity)
Color: Black
Cable form factor: flexible coaxial cable, small diameter
Intended use: indoor, short-range RF interconnection
How to use
Align the RP-SMA connectors with the mating RP-SMA female ports on each device and screw the connectors gently by hand until finger-tight. Avoid over-tightening with tools to prevent damage to connector threads. Route the cable without sharp bends; maintain gentle curves to preserve impedance characteristics and reduce insertion loss. For installations inside enclosures or behind equipment, secure the cable lightly to prevent strain on the connector ends.
Usage recommendations
Use this short RP-SMA to RP-SMA cable for indoor applications and test setups where minimal cable length is preferred. Keep the cable away from high-power RF sources and avoid outdoor exposure unless additional weatherproofing is applied. If a longer run or outdoor installation is required, select a cable with appropriate length and environmental ratings.
