SatelliteSale High-Frequency F81 Coaxial Barrel Connectors are perfect for connecting and extending your F-Pin coaxial cables. This compatible connector works with all your cable boxes, TV, satellite receivers, VCRs, cable modems, off-air antennas, or other digital AV devices. Applicable for both commercial and residential setups. Every SatelliteSale F-type F81 barrel connector we sell is manufactured from high-quality, weather-resistant material for exceptional termination quality and extremely low signal distortion. Moreover, F-type barrel connectors will not break, pull off, lose signal or become loose over time. As a result, enjoy the signal's clarity without distortion and signal loss, even at extended lengths. Flat port ends on each side of the connector ensure moisture ingress protection and maximum rejection of the hum/static from RF and EM interference. These barrel connectors are compatible with all the systems over coax. This includes Dish Network, Cable Vision, Verizon, Comcast, AT&T, Altice, DirecTV, and Charter. In addition, we assure the lifetime service of each coax cable to deliver a positive experience to our clients.
