Electrically the antenna is optimised for all exploitation conditions (radio on back, at the breast, on the ground, etc.) so it is not necessary for additional tuning. The antenna is composed of radiating part made of special steel multilayer tape material ensuring high flexibility and roughness. The antenna has built-in a special passive transformer tuning network enclosed in fibreglass housing above the input coaxial connector. Above the transformer unit is so called "goose neck" enables that the antenna is always in vertical position regardless of the position of the radio unit. Different models regarding the frequency range, max. RF power, input connector, etc., are available on request.
