Product Overview
Pomona 4786 is a BNC male coaxial connector designed for use with RG59, RG62, RG71, and RG210 cable types. Built for reliable signal connection in broadcast video, RF test, and instrumentation setups where a clean, mechanically sound BNC termination is required.
Key Features
- Connector type: BNC male
- Compatible cable types: RG59, RG62, RG71, RG210
- Nickel-plated body with knurled coupling ring for secure mating
- Gold center pin for low-resistance signal contact
- White PTFE insulator with red gasket for dielectric integrity
- Includes hex nut, ferrule, and flat washer - complete assembly set
- POMONA markings stamped on body; approximately 30mm body length
Applications
- Terminating RG59 or RG62 cable for custom patch leads used in broadcast and video production environments
- Building RF test cables for bench work - connecting signal generators, spectrum analyzers, or oscilloscopes with BNC inputs
- Repairing existing coaxial cable assemblies where the original BNC connector has failed or been damaged
- Ham radio operators assembling antenna feedlines or connecting transceivers to test equipment
- Retro computing and vintage video enthusiasts reconnecting monitors, capture cards, or composite video gear that uses BNC ports
- Makers and hobbyists adding BNC terminations to custom coax runs for audio, video, or RF projects
Frequently Asked Questions
Which cable types work with the Pomona 4786?
This connector is designed for RG59, RG62, RG71, and RG210 coaxial cables. Using it with other cable diameters or types is not recommended - the mechanical fit and termination integrity depend on cable dimensions matching those four types.
Does the listing include all the hardware needed to install the connector?
Yes. The unit includes the connector body, gold center pin, hex nut, ferrule, flat washer, red gasket, and PTFE insulator - the complete set of components for a single termination.
What termination method does this connector use?
Based on the components included - center pin, ferrule, and hex nut - this connector uses a combination of solder (center pin) and mechanical compression or crimp (outer body). Have the appropriate tools ready before installation.
Is this a 50-ohm or 75-ohm connector?
Impedance is not confirmed for this specific unit. BNC connectors for RG59/RG62 cable families span both 50-ohm and 75-ohm designs. Buyers with impedance-sensitive applications should confirm compatibility before ordering.
A Pomona connector from the days when labs kept a parts drawer full of exactly this - because the job of getting a clean BNC on the end of a cable never really changes. Now it is yours to put to work.
