Coaxial cable Rangeful RP-TNC male to RP-TNC female 3 m LMR400 UF UltraFlex

Coaxial cable Rangeful RP-TNC male to RP-TNC female 3 m LMR400 UF UltraFlex is a 3-meter RF cable with reverse-polarity TNC connectors on each end and an LMR400-style low-loss construction. The cable combines a robust center conductor and dielectric with a corrugated or braid shield to maintain signal integrity across UHF, VHF and microwave frequencies typically used in antenna feeds, wireless devices and radio test setups. An UltraFlex outer jacket improves bendability for tight routing and installations where movement or limited space is a factor.

Advantages

The cable delivers low insertion loss consistent with LMR400-class performance while keeping impedance stable at 50 ohms. RP-TNC male to RP-TNC female terminations provide the required reverse-polarity connection for compatible equipment and antennas. UltraFlex jacket material reduces stiffness compared with standard LMR400 constructions, simplifying routing through cable glands, conduits and equipment racks. The construction provides reliable shielding to minimise interference and maintain signal-to-noise ratio for RF links.

Suitable for

• Connecting routers, modems or radio transceivers with RP-TNC gendered ports
• Indoor and sheltered outdoor antenna installations and feeder runs
• Test benches and lab setups where flexible RF cabling is needed
• Short runs between external antennas and signal amplifiers or splitters

Key specifications

• Cable length: 3 m
• Connector types: RP-TNC male to RP-TNC female
• Impedance: 50 Ω
• Nominal construction: LMR400-class low-loss coaxial geometry
• Jacket: UltraFlex flexible outer jacket
• Typical frequency use: VHF/UHF and microwave bands commonly used in wireless systems
• Shielding: braided/corrugated shield for interference reduction

How to use

Verify that both devices accept RP-TNC gendered connectors and that a 50 Ω cable is appropriate for the RF system. Route the 3 m cable avoiding sharp bends and tight kinks; use the improved flexibility of the UltraFlex jacket to pass through conduits or around equipment. Hand-tighten the RP-TNC connectors to the mating ports without over-torquing; if available, use a torque wrench set to the connector manufacturer’s recommended torque. Inspect connections for secure seating and confirm signal levels with appropriate measurement equipment before finalising the installation.

Usage recommendations

For best long-term performance, protect cable runs from prolonged UV exposure and mechanical abrasion when used outdoors, and avoid repeated flexing at the connector strain relief. Use weatherproofing boots or appropriate sealing at outdoor terminations and keep cable length as short as practical to minimise insertion loss.
