UHF M CLAMP for 1/2″ Feeder Cable

Description

The UHF series is a rugged and reliable interface known for its high power-handling capabilities in HF and VHF applications. This male (plug) variant is specialized for 1/2″ foam dielectric feeder cable, providing a robust connection point for backbone antenna systems. Unlike standard crimp connectors, the clamp termination system uses a high-torque compression nut and an internal gasket to secure the cable’s outer conductor and jacket. This ensures a gas-tight, moisture-resistant seal and superior grounding without the need for specialized crimping tools in the field.

Maintaining a 50-Ohm nominal impedance, this connector is optimized to handle the significant physical and electrical demands of corrugated copper cables. It features a nickel or silver-plated brass body and premium PTFE (Teflon) insulation, allowing it to withstand the extreme temperatures and voltages associated with high-wattage transmitters. The clamp design is particularly valued for its mechanical strength, providing exceptional pull-off resistance and maintaining signal integrity even under high wind loads or vibration on radio towers.

Key Technical Advantages

• Feeder-Specific Engineering: Calibrated specifically for 1/2″ corrugated cables, ensuring a precise fit that prevents signal reflections and minimizes VSWR in long-run antenna feeds.

• Tool-Flexible Clamp Design: The heavy-duty nut and internal ring system allow for a professional, airtight termination using standard wrenches, making it ideal for field maintenance and tower-site installations.

• High Power & Voltage Stability: Built to manage the high wattage levels of amateur radio, paging, and maritime base stations without dielectric breakdown or overheating.

• Weather-Resistant Seal: The integrated clamp mechanism provides a high degree of protection against moisture ingress, essential for maintaining low attenuation in outdoor deployments.

• Superior Grounding Path: The massive brass construction and large surface contact area ensure an excellent ground connection to the cable’s outer conductor, critical for reducing EMI.

Key Features

• Interface Type: UHF Male (PL-259 Plug) with threaded coupling.

• Termination Method: Clamp / Compression for the outer conductor and Solder for the center pin.

• Cable Compatibility: Optimized for 1/2″ Superflex and 1/2″ Standard Corrugated feeder cables.

• Premium Construction: Features a plated brass body and high-performance PTFE dielectric.

• Common Application: Base station antenna installations, high-power RF amplifiers, and military communication infrastructure.
