Provides convenient routing and reliable connectivity in installations and field use.

## Long description

This Rangeful HF400-RPTNCM-SM-20 coaxial cable is a 20-meter UltraFlex lead with an SMA male connector on one end and a reverse-polarity TNC (RP-TNC) male connector on the other. Designed for RF signal transmission, the cable provides flexible routing and reliable connectivity for antenna connections, test equipment and communications gear that require standard SMA and RP-TNC terminations over an extended length.
Advantages
The UltraFlex construction allows easier handling and installation in confined spaces and field environments while maintaining signal continuity along the 20 m length. The combination of SMA male and RP-TNC male connectors ensures compatibility with devices that use these common RF interfaces. The cable is suitable for applications where a longer, flexible lead is needed without frequent connector conversions.
Suitable for
 Antenna connections for routers, modems and external antennas
 Laboratory and test setups requiring temporary or semi-permanent RF leads
 Field communications equipment and portable test instruments
 Installations where routing around obstacles requires a flexible long cable
Key specifications
 Cable type: UltraFlex coaxial cable
 Length: 20 m
 Connector A: SMA male
 Connector B: RP-TNC male (reverse-polarity TNC male)
 Intended use: RF signal transmission and antenna leads
How to use
Connect the SMA male end to the corresponding SMA female port on the device or antenna, and attach the RP-TNC male end to the RP-TNC female connector on the opposite device. Ensure connectors are threaded or secured per the connector type to maintain a stable connection. Route the cable to avoid sharp bends, kinks or crushing; allow gentle curves consistent with flexible coaxial cable handling. For test setups, place the cable so connections remain accesible for measurement equipment and avoid excess tension on connectors.
Usage recommendations
Inspect connector threads and mating interfaces before use to ensure clean, undamaged contacts. Avoid repeated flexing at the connector junctions and secure the cable with appropriate clamps or ties to prevent strain on the connectors. Match the cable to devices that accept SMA male and RP-TNC male terminations and verify system-level RF requirements such as frequency range and loss with your equipment documentation.
