Yaesu SCU-66 Extension Cable 5ft (1.5m) FTX-1 Optima

The SCU-66 is a 5-foot (152.4 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.
