The AD-25/CW-3512-TNC is a wideband VHF/UHF monopole antenna intended for use primarily on manpack radios in VHF/UHF frequency range from 30 to 512 MHz. The matching unit is composed of TNC male connector, a special passive transformer, gooseneck and tape radiator. A passive transformer is built in a hard plastic housing which enables durability of the use. Between the tape radiator and matching unit is a flexible goose-neck which allows bending the antenna to be always in vertical position. All metal parts of the matching unit are galvanically protected.
