Ancor RG213 250' Spool Low Loss Coaxial Cable

The Ancor RG213 250' Spool Low Loss Coaxial Cable is the professional-grade wiring solution serious vehicle builders and mobile installers depend on for radio, antenna, and communication system installations. Whether you're setting up a mobile ham radio platform, installing a CB system in a truck, or integrating marine-band communications into a vehicle, this 250-foot spool provides the length and signal integrity needed to route cable from dashboard-mounted equipment through firewall channels to roof-mounted or external antennas. RG213 cable is the industry standard for applications where signal loss must be minimized over longer runs, making it essential for any build that demands reliable, noise-free transmission.

Low-loss coaxial construction is what separates RG213 from lighter-gauge alternatives—the cable features a solid copper core, foam dielectric insulation, braided shield, and durable PVC jacket that resists automotive fluids, UV exposure, and mechanical abrasion during installation. This larger diameter cable (approximately 0.405 inches) provides superior shielding against electromagnetic interference and RF signal degradation compared to thinner RG58 or RG8X variants, ensuring clean audio and stable signal strength even across 250 feet of run. The 50-ohm impedance rating matches standard radio and antenna equipment, guaranteeing proper impedance matching and maximum power transfer without reflection losses that degrade performance.

Mobile radio enthusiasts, fleet mechanics, and custom vehicle builders benefit most from purchasing full spools rather than pre-cut lengths because you eliminate connector joints that introduce signal loss and failure points in critical runs. The 250-foot length accommodates full-size truck and RV installations, allowing you to run cable from engine bay radio mounts, through frame rails, under rocker panels, and up to root-mounted antennas without splicing. Installation is straightforward with standard PL-259, N-type, or SMA connectors crimped or soldered to cable ends—compatibility with virtually all CB, ham radio, and VHF/UHF transceivers makes this spool adaptable to fleet upgrades, hobby builds, and emergency communications setups alike.
