Coaxial cable Rangeful HF240-RPTNCM-NM-20 20 m, N male to RP‑TNC male

Rangeful HF240-RPTNCM-NM-20 is a 20 m coaxial cable assembly fitted with an N male connector on one end and a reverse polarity TNC (RP‑TNC) male connector on the other. Intended for RF and antenna connections, this fixed-length cable provides a ready-made link between devices with N and RP‑TNC interfaces. The construction is designed for general-purpose signal transmission in test benches, equipment interconnects and installations that require a pre-terminated coaxial feed.

Advantages

The cable offers a ready-to-use 20 metre length that eliminates the need for on-site termination and reduces installation time. The combination of an N male connector and an RP‑TNC male connector enables direct connection between common RF equipment and antennas or adapters without additional adapters. The fixed, pre-terminated assembly maintains consistent impedance along the run and simplifies setup for testing or permanent connections.

Suitable for

• RF test benches and laboratory measurements
• Connecting outdoor or indoor antennas to transceivers and radios with matching interfaces
• Temporary or semi-permanent installations requiring a durable pre-terminated cable
• Equipment interconnects between N-type and RP‑TNC type ports

Key specifications

• Cable length: 20 m
• Connector A: N male
• Connector B: RP‑TNC male (reverse polarity TNC)
• Cable type: coaxial RF cable (pre-terminated assembly)
• Intended use: RF/antenna connections and equipment interconnects

How to use

Inspect the connectors and cable for visible damage before installation. Connect the N male end to the corresponding N female port and the RP‑TNC male end to the matching RP‑TNC female port, ensuring threaded connectors are engaged and hand-tightened to provide secure mechanical and electrical contact. Route the 20 m cable to avoid sharp bends, kinks and prolonged compression; maintain gentle bend radii suitable for coaxial cable to preserve impedance characteristics. For outdoor use, ensure connections and any exposed sections are protected from moisture and mechanical strain according to site practices.

Usage recommendations

For reliable RF performance, avoid excessive bending and repeated flexing near the connector ends. Use compatible, properly rated adapters only when necessary and periodically inspect connector interfaces for corrosion or wear. When the cable is used outdoors, apply suitable weatherproofing at connector junctions and secure the cable to prevent strain on the connectors.
