ADS-21/4-W

The antenna ADS-21/4-W is wideband monopole mobile antenna covering frequency range from 68 to 88 MHz and is intended for use with mobile radio stations together with fixed antenna support type ADN-21/UHF-S or magnetic support ADM-21/UHF-S. The antenna is composed from two parts: the radiator which is made of special strong and flexible stainless steel whip with spring at the bottom and the matching transformer unit, which is enclosed in fibreglass tube. The antenna has standard UHF (PL-259) socket. The radiator and the matching unit are painted with UV protective polyurethane black paint.
