Weather-sealed coaxial coupler pack

This pack contains ten female-to-female barrel splices rated to 3 GHz for joining two coaxial video cables. The couplers suit installers and home users who need to extend RG58, RG59, RG6 or RG11 runs indoors or outdoors.

O-ring sealed metal construction

Precision-machined, corrosion-protected bodies include internal O-rings that seal out moisture while maintaining conductivity. A finger-grip profile lets you tighten each connection by hand without tools, and the female threads accept both 50-ohm and 75-ohm F-type plugs.

Broadband signal integrity to 3 GHz

The 3 GHz bandwidth supports cable modems, satellite receivers, HD antennas and CATV systems with minimal insertion loss. Shielded metal housings preserve picture, sound and data quality across the full frequency range in normal indoor or outdoor use.

Questions about this item

What frequency rating does the 3GHz barrel coupler support in practice?

The coupler is rated to 3 GHz, so it passes satellite IF bands, cable-modem DOCSIS channels and over-the-air TV frequencies without measurable loss.

Which coaxial cable sizes fit the female-to-female connector?

The barrel accepts RG58, RG59, RG6 and RG11 cables in both 50-ohm and 75-ohm variants.

How do you install the coupler without damaging the O-ring seal?

Hand-tighten each F-type plug until the O-ring seats, then give a slight quarter-turn with a wrench; over-torquing crushes the seal and lets moisture in.
