KJM Coax Cable & Extensions
KJM Coax Cable & Extensions: Marine-Grade Signal Solutions
When it comes to keeping your onboard electronics performing reliably on the water, the cable connecting your antenna to your radio or receiver matters just as much as the equipment itself. KJM has built its reputation over more than three decades in the marine industry by engineering products specifically for the demanding conditions sailors and boaters face — saltwater corrosion, UV exposure, constant vibration, and the tight routing constraints of a vessel's wiring runs. Their coax cable and extension lineup reflects that same focused, marine-first philosophy.
Purpose-Built for Marine Signal Transmission
KJM's coax cable and extension offerings are designed to serve the core connectivity needs of a modern vessel's communication and entertainment systems. Whether you're extending a VHF radio antenna, routing an AIS receiver cable through a bulkhead, or running a combined video and power cable to a shipboard camera, KJM has purpose-matched products for each application.
- AC201 VHF/AIS Antenna Extension Cable: A 20-foot RG-8X coaxial cable with FME connectors and an adapter, designed for use with KJM's own VHF and AIS antenna systems. RG-8X offers low signal loss in a flexible, smaller-diameter form factor — ideal for threading through tight spaces aboard a boat.
- AC301 AM/FM Extension Cable: A 20-foot RG62 cable with Motorola male and female connectors, made in the United States. This cable is purpose-matched for extending AM/FM antenna feeds to marine stereo receivers without sacrificing signal quality.
- COMB-25 Combination Coaxial Video/Power Cable: A 25-meter combined coaxial video and power cable terminated with BNC connectors — an efficient single-run solution for routing power and video signal simultaneously to KJM's shipboard camera systems.
Why Cable Quality Matters Aboard
In a marine environment, coaxial cable and its connectors are subjected to stresses that land-based installations rarely encounter. Moisture infiltration, flexing from wave action, and proximity to other electrical systems can all degrade signal quality over time. KJM's cables are engineered with the marine context in mind, ensuring that the signal reaching your VHF radio, AIS transponder, or stereo head unit is as clean and strong as possible — a consideration that can matter for safety as much as convenience.
As part of a broader ecosystem of KJM marine electronics, these coax cables and extensions are designed to pair directly with KJM's own antenna and camera product lines, simplifying compatibility decisions for installers and boat owners alike.
