150 ft RG8U Coaxial Cable with PL-259 Connectors

When your antenna is on the roof, in the attic, or mounted on a tower 150 feet away, signal integrity is everything. This heavy-duty RG8U coaxial cable delivers low-loss RF transmission across the full run — so what leaves your radio actually reaches your antenna, and what your antenna hears actually reaches your receiver.

Built for Serious Installations

RG8U (also known as RG-8/U) is a large-diameter, 50-ohm coaxial cable engineered for high-power, long-distance RF applications. Its thick center conductor and robust dielectric minimize signal attenuation even at HF and VHF frequencies — making it the go-to choice for CB base stations, 10-meter amateur radio setups, and fixed antenna systems where every dB counts.

Ready to Connect, Right Out of the Box

Both ends are factory-terminated with PL-259 (UHF) connectors — the industry-standard plug for CB and ham radio equipment. No soldering, no crimping, no guesswork. Just connect to your radio and your antenna and you're on the air.

  • Repeater and fixed-station setups

Why RG8U Over Thinner Coax?

Thinner cables like RG58 or RG8X lose significantly more signal per foot — acceptable for short runs, but a real problem at 150 feet. RG8U's larger diameter keeps attenuation low across the entire run, preserving transmit power and receive sensitivity where it matters most.
