Accordatore HF
The Yaesu FC-20 External Automatic Tuner is designed for the FT-100, FT-100/D and for the FT-847 operating on all HF ham bands plus 6 meters. It is ideal for tuning out minor SWR variations in your antenna system present at the radio end of your coax. Utilizing fixed inductances and variable capacitors controlled by precision stepper motors, the FC-20 can accommodate SWRs of up to 3:1 on HF and up to 2:1 on 50 MHz. The FC-20 also provides 100 memories for tuning data, so you will instantly be ready to transmit on your favorite frequencies and it includes a convenient Auto-Start feature in case the antenna system impedance suddenly changes.
