• Secure Cable Extension (Coupler): Functions as a heavy-duty UHF Female to Female Coupler to join two PL-259 male coaxial cables together. Unlike loose barrel connectors, this 4-hole flange design allows you to mount the connection point to a wall or desk for a permanent, tidy setup.
• UHF Gender Changer: Instantly turns two male PL-259 plugs into a continuous line. Perfect Gender Changer for bridging external antennas to indoor radio equipment through a bulkhead or enclosure wall.
• Chassis Mount Feed-Through: The ideal Feed-Through Adapter for Ham Radio Go-Boxes, truck bulkheads, or shack entry panels. The square flange ensures the connector never spins when tightening stiff cables (a common issue with round adapters).
• Universal Compatibility: Works with all standard 50 Ohm UHF Connectors (PL-259) used in CB Radio, Ham Radio (HF/VHF/UHF), Marine Radio, and Antenna Analyzers. Compatible with RG8, RG58, RG213, and LMR400 patch cables.
• Durable Build: Nickel-Plated Brass body with Gold-Plated contacts for reliable signal transmission. Requires 4 mounting screws (not included) for a vibration-proof install.
