Coax Cables

Coax Cables — CATV / Broadband — F-Connector Coax for Clean Signal Delivery
Common Types: RG-58 / RG-59 / RG-6 / RG-8 / RG-11
Use Cases: CATV, Cable Modem, MoCA, Satellite (as spec’d)
Terminations: F-Type (compression / crimp / twist-on)

Coax is still the backbone of CATV and broadband distribution—especially when you need long runs, strong shielding, and predictable performance across a wide frequency range. Our coax selection focuses on the details that actually matter: shielding quality, conductor type, attenuation, and connector integrity. Whether you’re wiring a headend, a rack, an MDF/IDF, or running drops to rooms, the right coax (and the right F connector) keeps the signal clean and the service calls low.

What makes a “good” CATV coax cable
  • Shielding that actually shields — foil + braid coverage reduces ingress/egress and protects MER/SNR.
  • Low loss / stable attenuation — especially important on longer runs and higher frequencies.
  • Conductor type — solid copper vs. CCS (copper-clad steel) depending on spec and application.
  • Jacket rating — choose the right rating for the pathway (indoor riser/plenum vs. outdoor/UV as required).
  • Connector fit & pull strength — a quality F termination prevents intermittent faults and reflections.
F-connector CATV cables: why terminations matter

A coax run is only as good as its ends. Poor terminations can create reflections, intermittent dropouts, water ingress, and shield leakage. We favor connector systems that deliver reliable compression, consistent impedance, and strong strain relief—so your installs stay quiet and stable over time.

Why buy from Gruber
  • Custom cuts — order exact lengths to reduce waste and speed installs.
  • Build-to-spec assemblies — need factory-terminated coax jumpers or bundles? We can build to your BOM.
  • Installer-focused selection — we stock coax that pulls cleanly and terminates consistently.
  • Real support — tell us your pathway, distance, and service type; we’ll help match the right coax and connector system.
