Yaesu SCU-66L Extension Cable 10ft (3m) FTX-1 Optima

The SCU-66L is a 10-foot (304.8 cm) cable, designed to connect the Field Head to the SPA-1 100W RF Power Amplifier.

These extension cables make it possible to install the Field Head and SPA-1 in separate locations—ideal for mobile setups. For example, the Field Head can be mounted on a dashboard while the SPA-1 is installed in the boot or under the front set, offering a clean and flexible solution for in-vehicle operation.
