The Yaesu SPA-1 is the dedicated 100W HF/50MHz (6-meter) power amplifier originally included with the FTX-1 Optima base station package. Now available separately, the SPA-1 allows FTX-1 Field owners to seamlessly expand their portable transceiver into a powerful base station, offering the ultimate flexibility of a single radio for both field and home operations.
By easily connecting the SPA-1 to the rear of your FTX-1 Field Head, you instantly gain a significant power boost, achieving 100W output on the HF bands and 50W output on the 144MHz (2-meter) and 430MHz (70cm) VHF/UHF bands. This increased power dramatically improves your transmission range and signal strength for more effective communication from your base station.
