Brass F81 barrel connectors with blue insulators, pack of 50

The Wires Zone

The Wires Zone F81 Splice 3/4" Long Barrel 50 Pack

SKU CH-86K0-HKPZK

Pack of 50 F81 couplers join RG6 or RG59 coax with 2.5 GHz bandwidth and 0.20 dB insertion loss

  • Supports 2.5 GHz broadband signals for reliable high-frequency performance
  • SCTE IPS-SP-407 compliant flat-ended port ensures improved contact and high return loss
  • Precision-machined CDA360 brass construction provides durability and consistent connectivity
  • 360° round seizing center contact delivers high spring tension for repeat insertions
  • Pack of 50 female-to-female adapters connects RG6 or RG59 coax cables

2.5 GHz F81 Splice 3/4" Barrel

This pack contains fifty F81 splice connectors rated to 2.5 GHz for joining RG6 or RG59 coaxial cables. The female-to-female design suits broadband network and distribution installations up to 3 GHz. Installers and system integrators use them for cable repairs, extensions or distribution points. Buyers who need push-on or compression F connectors will require different hardware.

Precision Brass Construction SCTE Compliant

Each coupler uses precision-machined CDA360 brass with a flat-ended small-aperture port that meets SCTE IPS-SP-407 for improved contact and high return loss. A 360° round seizing centre contact provides high spring tension for repeat insertions. The blue insulator uses phosphor bronze. These features reduce signal degradation at the joint.

Low Loss 0.20 dB 8 Amp Current

Insertion loss is 0.20 dB maximum and return loss is -24 dB minimum at 2.5 GHz, preserving signal quality across the splice. The connector handles 8 amperes DC continuous current for power-passing applications. Runs exceeding the rated frequency or current will exceed the specified performance envelope.

Questions about this item

Will the phosphor-bronze centre contact need replacing after many reconnections?

The 360° round seizing contact delivers high spring tension rated for repeat insertions, so the phosphor-bronze centre contact is designed to last without scheduled replacement.

What limits signal quality first when the adapter runs continuously at 2.5 GHz?

Insertion loss is capped at .20 dB maximum and return loss at -24 dB minimum at 2.5 GHz, so attenuation and reflection thresholds are the first limits encountered.

Does the brass body run hot or draw noticeable power during all-day use?

The connector is passive with an 8-ampere DC continuous current rating and no active components, so it generates no measurable heat and consumes no power of its own.
