RFAdapter RG8x 100ft Coaxial Cable PL259 50Ω

RFAdapter RG8x 100 ft coaxial cable is a low-loss, 50-ohm UHF (PL259) cable built for CB and ham radio setups that need durable copper conductors, double shielding and reliable outdoor performance.

Whether you’re feeding an antenna on a vehicle, connecting an SWR meter, or pairing an antenna analyzer with a dummy load, this 100-foot RG8x cable delivers a balance of flexibility, signal integrity and weather resistance. Constructed with a 17 AWG pure copper inner conductor, double shielding and molded nickel-plated PL259 connectors with gold-plated center pins, it’s designed to limit signal loss up to 300 MHz while staying rugged enough for permanent installations.

How does this cable reduce signal loss compared with standard coax?

The RG8x design uses a thicker 17 AWG pure copper center conductor and dual shielding that together cut resistance and block electromagnetic interference. That means less attenuation across long runs compared with thinner cables like RG58, and more stable SWR readings for transmitters and analyzers.

• Pure copper 17 AWG center conductor for lower resistance.
• Double shielding to reduce RFI/EMI and prevent leakage.
• Optimized for 50 ohm systems to maintain matching across runs.

Will the PL259 connectors withstand outdoor use and frequent hookups?

Yes — each end is fitted with fully molded nickel-plated brass UHF PL259 connectors and a gold-plated center pin to resist corrosion and preserve contact quality. The molded construction reduces stress at the solder points and the PVC jacket adds water resistance for exterior routing.

• Nickel-plated brass PL259 housings for corrosion resistance.
• Gold-plated center pins for stable conductivity over time.
• Molded ends reduce mechanical failure from bending or tugging.

What devices and installations is this 100 ft RG8x cable compatible with?

This 50-ohm RG8x cable works with a wide range of RF equipment commonly used by amateur radio operators and mobile CB users. It pairs with ham transceivers, CB radios, antenna tuners, SWR meters, antenna analyzers, and dummy loads without requiring adapters when using standard PL259/SO-239 connections.

• HAM and CB radios, mobile and base station setups.
• Antenna analyzers, SWR meters, tuners, and dummy loads.
• Perfect length for vehicle-to-tower or rooftop antenna runs.

How durable and flexible is the cable for installation and routing?

The cable’s flexible PVC outer jacket makes routing through tight spaces and grommets easier than rigid coax types, while remaining resilient against weather exposure. Its construction balances bendability with strain resistance so it won’t kink easily and will hold up when run along vehicle frames, masts or walls.

• Flexible PVC jacket for easier routing and outdoor resilience.
• Stronger build than average CB cables to resist wear and tear.
• Suitable for permanent installations or mobile use like Jeep CB setups.

Who is this for? Radio hobbyists and professionals who need a dependable long-run coax with better performance than RG58 will appreciate this RG8x 100-foot cable. It’s aimed at operators installing rooftop or vehicle antennas, technicians who use analyzers and SWR meters, and anyone who wants a weather-resistant, low-loss 50-ohm connection for frequencies up to 300 MHz.
