Foam-Dielectric Coaxial Cable

Shop foam-dielectric coaxial cable for wireless, telecommunications, DAS, broadband and RF infrastructure. Foam coax cable uses a cellular dielectric layer between the center conductor and outer conductor to support low-loss radio-frequency transmission. It is commonly installed as a feeder cable between RF equipment, antennas and other components throughout commercial communications networks.

This collection features low-loss foam-dielectric coaxial cable in standard, flexible and ultraflexible configurations. Available cable diameters include 1/2-inch, 7/8-inch, 1-1/4-inch and 1-5/8-inch options for different RF transmission layouts. Many cables are offered by the foot, allowing contractors to purchase material for planned tower, rooftop, equipment-room and in-building cable runs.

Foam dielectric coax is used throughout cellular networks, macro tower sites, rooftop antenna systems, distributed antenna systems, two-way radio networks and broadcast infrastructure. It connects radios, antennas, RF distribution equipment and other compatible components that require a 50-ohm coaxial transmission line. Larger feeder cables support primary RF routes, while flexible and ultraflexible coaxial cable can accommodate areas with more involved routing.

The combination of a foam dielectric and corrugated cable construction supports RF signal transmission across telecommunications installations. Foam coaxial feeder cable is used for both new network construction and existing system upgrades, including antenna additions, equipment replacements and changes to established cable routes. Multiple cable profiles allow the same category to serve outdoor wireless sites and indoor RF distribution projects.

A complete coaxial cable installation also uses compatible connectors, hangers, grounding components, entry hardware and weatherproofing materials. Coax connectors terminate the cable at antennas and RF equipment, while cable support hardware organizes vertical and horizontal runs. Grounding kits and related bonding components connect the coaxial system to the site grounding network.

Explore additional coaxial cable, including superflexible coaxial cable and plenum coaxial cable. Complete cable terminations with coaxial connectors, coaxial adapters and cable preparation tools.

Support and protect RF cable runs with snap-in hangers, coax blocks, clip-on ground kits and cold-shrink weatherproofing. Launch 3 Telecom supplies foam-dielectric coaxial cable and installation accessories for tower crews, wireless contractors, DAS integrators, broadband providers and RF infrastructure teams.
