- White waterproof PVC jacket suits outdoor marine use
- 2 in heat shrink reinforces PL259 connectors
Marine CB Antenna Cable
This 50 ft RG8x coaxial cable is built for VHF marine, CB, HAM and SWR-meter installations where a white jacket is preferred. Solid copper centre conductor with aluminium-foil and tinned-copper braid gives more than 95 % shield coverage for EMI and RFI resistance. PL259 male connectors at both ends suit standard UHF fittings on radios and antennas.
Low-Loss Signal Transfer
RG8x construction reduces attenuation compared with RG58 cable, supporting cleaner reception and transmission over the full 50 ft run at higher frequencies. The waterproof white PVC jacket withstands outdoor exposure on boats or masts without degrading. Heat-shrink reinforcement protects the connector junction during repeated connect and disconnect cycles.
Reinforced Connector Strain Relief
Each PL259 plug is secured by a 2.2 in heat-shrink tube that grips the cable and connector body, reducing the chance of pull-out or fatigue failure. Flexible jacket material eases routing through bulkheads, conduit or rigging while maintaining a watertight seal. White colouring avoids heat absorption on deck and simplifies visual tracing among other wiring.

Questions about this item
How do I install the PL259 connectors on this 50ft RG8x cable, and what step is often missed?
Screw each PL259 male connector onto the matching UHF female port by hand until snug, then give a final quarter-turn with a wrench; the step many miss is checking that the 2.2in heat-shrink sleeve sits flush against the connector body to seal out moisture.
What maintenance or replacement will this coaxial cable need over time?
Inspect the white PVC jacket annually for UV cracking or abrasion, reseal any exposed conductor with marine-grade tape, and replace the cable if the braid shows corrosion or the 95% shielding effectiveness drops below spec.
What limit appears first when this RG8x cable runs at high power for long periods?
The 50ft length and RG8x dielectric set the practical power ceiling; sustained high-power transmission will heat the solid-copper centre conductor first, increasing attenuation before the 95% shield or PL259 joints become the bottleneck.
