Coaxial cable Cabletech KHR/RG174U 50 Ω 2.8 mm black

Cabletech KHR/RG174U is a 50 Ω coaxial cable with a 2.8 mm outer diameter and black PVC jacket. It features a copper conductor (7x0.16 mm) and a copper braid shield (64x0.1 mm) providing consistent impedance and shielding for RF and signal transmission in antennas, radio equipment and test instruments. The cable is compact and flexible, suitable for short to medium cable runs and installations in confined spaces where a standard 50-ohm coax is required.

Advantages

The cable offers stable 50 Ω impedance and robust copper shielding for reduced interference. Its small 2.8 mm diameter and flexible PVC jacket facilitate routing in tight spaces. Specified attenuation values across a wide frequency range allow predictable signal loss planning for RF and testing applications.

Suitable for

• Antenna connections and feeder lines
• Radio transceivers and receivers
• Test and measurement setups
• Short to medium length patch leads and internal wiring in equipment

How to use

Strip the outer jacket and dielectric according to the connector manufacturer’s instructions to avoid damage to the 7x0.16 mm copper conductor and the 64x0.1 mm braid. Install appropriate 50 Ω RF connectors (e.g., SMA, BNC, or others compatible with RG174 form factor) and ensure secure mechanical and electrical contact. Route the cable without sharp bends and avoid crushing to maintain impedance and minimize additional losses.

Usage recommendations

For best results use this cable for short to medium runs where flexibility and small diameter are required. Minimize cable length at higher frequencies to reduce attenuation; consider lower-loss alternatives for long high-frequency runs.
