UHF Female to N Female 4H Flange Adapter

Description

The UHF Female to N Female 4-Hole Flange Adapter is a specialized “between-series” RF component designed for secure mounting on chassis, cabinets, or equipment panels where rotational stability and high torque resistance are critical. It features a UHF Jack (Female/SO-239) on one side and an N-Type Jack (Female) on the other, integrated into a single body with a precision-machined square flange. The flange includes four pre-drilled mounting holes, allowing the adapter to be bolted directly to a surface to ensure it remains stationary during the connection of heavy-duty cable assemblies.

This adapter is indispensable for engineers and radio operators who require a rugged, external N-Type interface for internal UHF-terminated circuitry, or vice versa, in environments subject to physical stress or vibration. The 4-hole flange design distributes mechanical load across the panel, preventing the connector from loosening or spinning when high-torque N-Type or UHF PL-259 male plugs are mated. Constructed with a heavy-duty nickel-plated brass body and PTFE (Teflon) insulation, it maintains reliable mechanical and electrical contact for high-power broadcast and wireless infrastructure applications.

Key Technical Advantages

• Four-Hole Flange Stability: The integrated square flange provides a superior mechanical anchor compared to standard bulkhead mounts, preventing rotation and ensuring long-term alignment under heavy usage.

• Interface Versatility: Enables the direct connection of rugged N-Type cables to traditional UHF-based communication hardware through a secure panel wall.

• Precision RF Pass-Through: Serves as a high-quality bridge for routing signals through equipment enclosures while maintaining mechanical integrity.

• Superior EMI/RFI Shielding: The broad surface contact of the 4-hole flange against the metal chassis provides an exceptional ground path, significantly reducing signal leakage and environmental interference.

• Maximum Conductivity: High-purity gold or silver plating on both internal center contact sockets ensures ultra-low contact resistance and superior protection against oxidation.

Key Features

• UHF Female to N Female Interface: Consists of a UHF Jack (SO-239 with socket and threads) and an N-Type Jack (with socket and threads).

• Integrated 4-Hole Square Flange: Precision-machined for secure bolting to equipment panels, preventing rotation and mechanical failure.

• Nickel-Plated Brass Construction: Offers superior corrosion resistance and professional-grade durability for both indoor and outdoor applications.

• Premium PTFE Dielectric: Provides high thermal stability and maintains consistent electrical performance across its operating range.

• Industrial Durability: Rated for at least 500 mating cycles, ensuring long-term reliability in high-traffic broadcast and field communication systems.
