ADxx0x series is a single or dipole array wide band VHF/UHF antennas for extensive range of applications trunking radio systems, military communications, dispatch base stations, amateur radio repeaters, etc. More gain is achieved by coupling single folded dipoles into arrays.
The horizontal radiation pattern is adjusted by changing the distance between dipole elements and supporting mast. AD 1502 is a two-dipole element array wide band VHF antenna for professional radio systems. Dipole incorporates balun matching circuit optimized for wide bandwidth and accurate matching.
Dipoles in array are coupled by precision phasing cable harness keeping low SWR and minimum insertion losses. All antenna parts are made of aluminium and covered with polymer powdered coating which resists water and ice buildup, and provides exceptional protection from corrosive gases, UV radiation, salt spray, acid rain and windblown abrasives.
All components of dipole elements are DCgrounded for better lighting and antistatic protection. Feeder connection is carried out through the connector N female. The mounting of the dipole crosspiece is designed to be placed on masts and pipe racks with an outer diameter of up to 55 mm. The mast (pipe rack) in the antenna kit is not supplied.Frequency range, MHz 136 176. Pattern Adjustable: Offset circular, cardioid, or bidirectional. Gain, dBd 5,6 (3/8 dipole to mast spacing). Overall dimensions, mm H 2200 3/8 spacing, W 1100.
