STEREN RG8X 75 ft Coaxial Cable PL-259 UHF 50Ω

STEREN RG8X Coaxial Cable 75 ft is a low-loss, 50-ohm UHF-to-UHF (PL-259 to PL-259) jumper built for HAM, CB and high-powered antenna applications.

This 75-foot (22.86 m) RG‑8X cable from STEREN combines a thicker 0.242" diameter construction, foam polyethylene dielectric and premium shielding to reduce signal loss compared with RG‑58. It arrives terminated with fully molded, nickel-plated PL‑259 (UHF) male connectors soldered to an oxygen‑free stranded copper core. The black PVC jacket and durable braid/foil shields make it suitable for both indoor and outdoor runs where reliable RF transfer is needed.

How does this cable reduce signal loss compared to standard RG-58?

The RG8X build uses a larger conductor and denser shielding than RG‑58, lowering attenuation over long runs. Its foam dielectric preserves impedance consistency and the combination of foil plus a heavy braid improves shielding against RF interference.

• 50 ohm characteristic impedance for match to most amateur and CB setups
• Thicker 0.242" outer diameter reduces resistive loss
• Aluminum foil + high-quality braid for superior EMI/RFI rejection
• Oxygen-free stranded copper center for better conductivity

Are the PL‑259 connectors weatherproof and reliable for field use?

Each end is fitted with a fully molded PL‑259 plug plated in nickel for corrosion resistance and mechanical durability. The connectors are factory-soldered to the core, lowering the chance of intermittent joints and improving long-term reliability in vehicle and stationary antenna installations.

• Molded connector bodies reduce moisture ingress at the junction
• Nickel plating helps resist rust in outdoor environments
• Factory soldered terminations ensure consistent electrical contact
• Designed for repeated connect/disconnect cycles without loosening

What installations and radios pair well with this 75 ft RG8X cable?

This 75-foot jumper is a versatile choice for base and mobile setups where a low-loss feedline matters—HAM transceivers, CB radios, antenna analyzers and SWR meters all benefit. Its length gives placement flexibility for rooftop antennas or long runs to a shack without quickly sacrificing signal strength.

• HAM and CB base stations, mobile installs, and vehicle antenna feeds
• HF and VHF antenna connections where 50Ω is required
• Use with tuners, analyzers, SWR meters and antenna switches
• Useful for temporary field operations or permanent rooftop runs

How durable is the cable for outdoor exposure and handling?

The black PVC jacket resists abrasion and UV to a practical degree for typical rooftop and mast installs; the internal shield layers maintain electrical integrity even when flexed. For extended outdoor immersion or extreme marine use, additional sealing or conduit is recommended.

• Sturdy PVC outer jacket for abrasion and light UV resistance
• Foam polyethylene dielectric retains shape and performance over time
• Robust braid and foil shielding maintain low loss despite movement
• Best practice: use sealing tape or boots for long-term exterior exposure

Who is this for? Installers, amateur radio operators and CB users who want a cost-effective upgrade from RG‑58 will appreciate the STEREN RG8X 75 ft jumper. It’s aimed at those who need a longer run with reduced attenuation, dependable factory-terminated PL‑259 connectors, and a cable build that balances flexibility with improved electrical performance. If you’re setting up a base station, running an HF/VHF antenna, or preparing a mobile/vehicle antenna feed where 50 Ω impedance and durable connectors matter, this cable is a practical choice.
