Coaxial cable Rangeful HF400 TNC Male–TNC Male 50 Ω, 20 m

Rangeful HF400 coaxial cable with TNC male connectors on both ends is a 20 m, 50 Ω RF cable engineered for reliable signal transmission and antenna connections. The cable combines a standard impedance match with TNC male terminations to provide a stable interface for radio systems, test equipment and repeater installations. Its length and flexibility allow extended link runs while maintaining consistent electrical characteristics across the line.

Advantages

The cable offers a uniform 50 ohm impedance suitable for most RF applications, minimizing reflections and preserving signal integrity. Standard TNC male connectors ensure secure threaded mating and compatibility with a broad range of RF devices. The HF400 construction provides mechanical flexibility for routing and installation in cramped spaces while maintaining shielding to reduce interference. A 20 m length reduces the need for multiple cable joins, lowering potential points of failure.

Suitable for

• Antenna connections for radio transceivers and base stations
• Connecting test equipment, spectrum analyzers and signal generators
• Linking repeaters, routers or other outdoor RF equipment where a threaded connector is required
• Temporary or permanent installations that require 50 Ω impedance continuity over longer runs

Key specifications

• Impedance: 50 ohm
• Length: 20 m
• Connector type: TNC male to TNC male
• Cable family: HF400-style coaxial
• Typical use: RF signal transmission and antenna feedlines

How to use

Connect one TNC male end to the device or antenna port and thread the connector until hand-tight; use a torque wrench only if the mating device specifies a torque value. Route the cable to avoid sharp bends that could deform the dielectric or outer conductor; maintain gentle bends with radii larger than the cable diameter. If the run passes through walls or enclosures, use appropriate grommets or conduit to protect the cable jacket. For outdoor use, protect connectors from moisture with suitable sealing methods.

Usage recommendations

Verify that all mating ports are 50 Ω and accept TNC male connectors before connecting. Keep cable runs as short as practical to reduce insertion loss, and avoid kinking or repeated flexing at connector interfaces. Periodically inspect connector threads and jacket integrity; replace the cable if shielding or connector performance degrades.
