CB Coax Cable 100ft RG8x PL259 Male to Male - Low Loss Marine Cable

In this review of the 100ft CB Coax Cable RG8x, the bottom line is clear: this cable is aimed at hobbyists and boat owners who need a longer, low-loss run between radio and antenna. The reviewer found the cable delivers noticeably lower signal loss than typical RG58 on VHF and HF uses, making it a practical upgrade for CB, HAM and marine VHF installs. Installation is straightforward for anyone comfortable with bulk coax, and the white PVC jacket makes it especially useful on boats or places where a white lead looks cleaner.

Key Features

• Ultra low loss: The RG8x (Mini-8) construction reduces signal attenuation compared with RG58, helping preserve signal strength over the 100ft length.
• Marine-friendly jacket: The white PVC outer jacket resists outdoor exposure and blends well on boats or light-colored runs.
• Solid inner conductor: A solid copper core improves conductivity and consistency for radio signals across VHF and HF bands.
• High shielding: Aluminum foil plus tinned copper braid provides over 95% shield coverage to reduce EMI and RFI on crowded frequencies.
• Upgraded connector protection: A 2.2in heat shrink section secures the PL259 connector to the cable and lowers the chance of connector separation.
• Wide compatibility: Works with CB radios, HAM equipment, SWR meters, antenna analyzers and VHF marine antennas for flexible use.

Who It's For

This cable is best for amateur radio operators, marine users and anyone replacing a long run of RG58 with a lower-loss alternative. The 100ft length suits installations where the radio and antenna are separated by some distance, and the white jacket is a plus for boat decks or light-colored cable channels.

Those who need an ultra-flexible coax for tight bends or who want a premade cable with weatherproof, crimp-style connectors should look elsewhere; the RG8x is firmer than RG58 and most buyers will want to plan routing to avoid sharp bends.

Pros & Cons

Pros

• Lower signal loss than RG58 over long runs, which improves effective range and performance.
• White PVC jacket suited to marine and outdoor use with decent weather resistance.
• Strong shielding and solid copper conductor help reduce interference and maintain signal integrity.

Cons

• Cable is relatively stiff compared with thinner coax, which can make tight routing more difficult.

Our Verdict

The 100ft RG8x CB Coax Cable is a sensible upgrade for users who need a longer, lower-loss run for CB, HAM or marine VHF setups. It balances shielding, conductor quality and a marine-friendly white jacket at a reasonable value; choose this for installations where loss matters and rigidity is acceptable.

Frequently Asked Questions

Is this cable suitable for marine VHF antennas?
Yes, the white PVC jacket and low-loss RG8x construction make it appropriate for marine VHF antenna runs where a white cable is preferred.

Will this work with my SWR meter or antenna analyzer?
Yes, the PL259 male ends and low-loss characteristics make it compatible with SWR meters, antenna analyzers and most CB/HAM gear that uses UHF connectors.

How flexible is the cable for tight installations?
The RG8x is firmer than RG58, so it handles reasonable bends but is not ideal for very tight, convoluted routing where extra flexibility is required.
