The VHF handheld antennas AD-44/BW represent a family of wideband monopole whips, primarily intended for use with portable and handheld radios in VHF frequency range from 30 to 90 (108) MHz. Electrically the antenna is optimised for all exploitation conditions (radio in hand, at the side, etc.) so it is not necessary for additional tuning. The antenna is composed of radiating part made of special wounded wire or helix and covered with a heatshrinkable tube with silicone undercover ensuring high flexibility and roughness. The antenna has built-in a special passive transformer tuning network enclosed in fiberglass housing above the input coaxial connector. Input connector is TNC male. Other types (N or BNC male) are available on special request.
