Yaesu ATAS-25 Manual Tuning Portable Antenna 7–430MHz, 100W, Tripod Mount

Yaesu ATAS-25 Manual Active Tuning Antenna

The Yaesu ATAS-25 is a versatile, manually-tuned portable antenna covering 7 to 430MHz across seven amateur bands. Unlike motorised ATAS antennas, the ATAS-25 uses a manual tuning system to resonate the radiating element for the lowest SWR — eliminating the need for expensive mono-band whip assemblies. It supports dual-frequency operation on HF or 50MHz combined with either 2m or 70cm (duplexer not supplied). Designed to mount directly onto a standard camera tripod, it's an excellent choice for portable, SOTA, POTA, or temporary field operation.
