150 ft RG8U Coaxial Cable with PL-259 Connectors
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.

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.
