AD-25/WB-3512: VHF/UHF wideband dipole long manpack/handheld antenna (30 - 512 MHz)

The AD-25/WB-3512 is a wideband VHF/UHF dipole ("center-fed") manpack / handheld antenna, primarily intended for use with manpack portable radio units in VHF/UHF frequency range from 30 to 512 MHz. Electrically the antenna is optimized for all exploitation conditions (portable radio unit on operator body, hand, ground, etc.) so it is not necessary to additionally tune the antenna. The antenna is composed of six basic elements (from the bottom up): Current-choke unit, flexible goose-neck, matching unit, flexible goose-neck, coil unit, and tape radiator. The current-choke unit allows the antenna to be independent of the portable radio unit and so forms a correct dipole shape. Flexible goose-neck allows bending the antenna to be always in a vertical position. Matching unit with a special built-in passive transformer tuning network is enclosed in a plastic housing. Tape radiator is made of flexible tapes covered with a plastic tube ensuring high flexibility and roughness. The antenna connector is a TNC male or N male.
