Yaesu ATAS-25

The ATAS-25 is a manually-tuned portable antenna system ideal for the FT-817, FT-897, and FT-857 transceivers. Capable of operating on the Amateur bands between 7 MHz and 450 MHz, the ATAS-25 is designed for mounting on a standard 1/4" camera tripod stud (tripod not supplied), and includes an innovative fine-tuning system allowing precise SWR adjustment in the field.

Please note, due the separate connectors for HF and VHF/UHF frequencies in specific radios you may want to purchase duplexer or triplexer for operation on the 144/430MHz. Otherwise you have to move coaxial cable connector to appropriate antenna jack when you wish to operate on VHF or UHF.
