Key Facts

225 MHz to 400 MHz UHF transmitting/receiving antenna for naval applications

The vertically polarized omnidirectional antenna R&S®AD066ST covers the frequency range from 225 MHz to 400 MHz. Four dedicated receive/transmit systems with up to 200 W transmitter power each can be used with the antenna. Due to the antenna's decoupling characteristics, particularly between its upper and lower part, it can be operated in receive and transmit mode even with close frequencies.

The R&S®AD066ST is characterized by very good omnidirectional characteristics and a high gain.

The R&S®AD066ST is equipped with a self-supporting radome made of glass-fiber reinforced plastic (GRP).
