The Yaesu ATAS-120 Active Tuning Antenna System provides HF/VHF/UHF coverage with automatic motorized tuning. It is the successor to the popular ATAS-100. Utilizing control signals from the transceivers microprocessor received via the coaxial cable, the ATAS-120's internal motor adjusts the radiator length for best SWR.

中间的某个地方，FT–891承诺提供一个现代化且功能更强大的数字模式台站，这是一台用于度假的电台，需要外接电池，但便携性足以走进农村地区。 今年早些时候，我从当地的业余无线电商店购买了一台新产品，接下来是到目前为止我对这款电台在短波收听的发现和观察。 我最近一次使用FT–891进行的林地探险使我有机会将其制作的录音，并将其与我使用过的其他收音机录音进行比较。 最显着的差异是音频频谱下部缺少频率，并且在5kHz处有明显的截止频率。 在下面的FT …

The is a unique mobile antenna designed for use with Yaesu the transceivers equipped for the ATAS system, such as the FT-897, FT-847, FT-857 and FT-100/-100D. The utilizes a motorized tuning system which resonates the radiating element for lowest SWR without the need for expensive, inconvenient monoband resonating whip assemblies.

The ATAS-120A is the upgraded, more weather resistant version of the ATAS-120. Leave comments only on the ATAS-120 "A"!
