Yaesu ATBK-100 – VHF/UHF Counterpoise Kit for ATAS Antennas

The Yaesu ATBK-100 is a specially designed VHF/UHF counterpoise kit for use with the ATAS-100 and ATAS-120 active tuning antenna systems. It enhances antenna performance on the 50MHz, 144MHz, and 430MHz bands, making it an essential accessory for operators using the ATAS series on balconies or other limited-space installations.
