The Yaesu 40M-WP (catalog reference C-40MWP) is a high-grade 40-metre pre-assembled control cable harness engineered specifically to interface the indoor desktop controller with the outdoor rotator drive unit across Yaesu antenna rotator systems. Fully terminated and factory-pinned at both ends with genuine connectors, it provides an immediate “plug-and-play” installation, completely doing away with the need to measure conductors, strip jackets, or solder multi-pin connectors atop the tower or in the radio shack.
Built with a heavy-duty 10 mm (1 cm) UV-resistant and weather-sealed outer jacket, the assembly houses 6 stranded copper conductors sized to prevent voltage drop along the motor line over its full 40-metre run, ensuring dependable rotation torque and precise azimuth potentiometer feedback. The outdoor rotator end features a rugged 7-pin circular metal plug equipped with a moulded rubber weather boot that locks securely onto the motor housing to block out moisture and rain, while the indoor end is terminated with the dedicated rectangular multi-pin plug for a direct connection behind the controller.
Key Advantages
- Genuine Plug-and-Play Assembly: Factory-terminated and continuity-tested at both ends, eliminating soldering, crimping, and pinout errors during tower installation.
- Generous 40-Metre Reach: Ample length to easily bridge the run from an indoor operating position or shack to the rotator platform on lattice towers, roof masts, or poles.
- Weather-Sealed Outdoor Termination: Black circular 7-pin metal connector fitted with an elastomeric weatherproof rubber boot to protect electrical contacts against ingress.
- Ruggedised Heavy-Duty Sheathing: 10 mm outer diameter jacket engineered for superior abrasion resistance, torsional flexibility in high winds, and long-term UV resistance.
- Optimised Conductor Sizing: Low-resistance internal wiring designed to minimise voltage drop across the DC drive motor over the entire 40-metre span.
Recommended Applications
Guyed and Self-Supporting Tower Installations
Provides a single continuous run from the radio shack directly to the tower-top rotator without needing junction boxes or field splices.
Commercial and Residential Roof-Mounted Masts
An ideal pre-wired solution for clean cable routing through building conduits, riser ducts, or exterior walls with factory-certified weather sealing.

Frequently Asked Questions
Is any soldering or wiring required prior to installation?
No. This cable comes fully assembled, wired, and continuity-tested from the factory. You simply plug the weatherproof metal connector into the rotator housing and the rectangular plug into the back of your desktop controller.
Which Yaesu rotators are compatible with this cable?
It is fully compatible with modern Yaesu rotator models equipped with standard round multi-pin motor sockets, including the G-450, G-450CDC, G-800DXA, G-800DXC, G-1000DXA, and G-1000DXC.
Can this cable be trimmed if the 40-metre length is too long?
While the cable could technically be cut and re-soldered, it is not recommended unless strictly necessary, as altering the harness removes the factory-moulded strain relief and heat-sealed weatherproofing.
