Dolphin Components BNC Coax Coupler 10-Pack

This pack contains ten BNC male crimp-on couplers designed for RG-8 and RG-11 coaxial cable. They suit installers terminating thick low-loss runs in broadcast, RF distribution or instrumentation systems. Each connector uses a three-piece brass body with nickel plating for corrosion resistance. The components meet RoHS compliance standards.

Sustained RF Performance up to 4 GHz

The couplers maintain 75 ohm impedance through the joint up to a maximum frequency of 4 GHz. Nickel-plated brass construction resists oxidation that would otherwise raise VSWR over long service periods. The crimp method creates a gas-tight seal that prevents moisture ingress on outdoor masts. Silver finish aids visual inspection of contact quality.

Three-Piece Crimp Installation Notes

Termination requires a compatible crimp tool and die set for RG-8 or RG-11 cable diameters; the tool is not included. Stripping lengths must follow the connector’s internal geometry to avoid shorting the centre pin. Over-crimping can distort the dielectric and shift impedance. Buyers without crimp tooling should consider compression or twist-on alternatives.

Questions about this item

How much heat does the DC-MC78-26 generate during continuous RF transmission?

The nickel-plated brass body and crimp-on design add no active components, so the coupler itself produces no measurable heat during all-day operation.

What cable preparation and tools are required to install these BNC male couplers?

You need RG-8 or RG-11 coaxial cable, a compatible crimp tool for the three-piece crimp-on design, and basic stripping tools for the centre conductor and braid.

Will the 75 ohm impedance of the DC-MC78-26 match older 75 ohm BNC gear in my rack?

Yes, each coupler is rated for 75 ohm maximum impedance and 4 GHz, so it will interoperate with legacy 75 ohm BNC equipment without impedance mismatch.
