220 MHz (200-260) Dipole array ,VHF 4-element antenna 9 DBd 300W

Description

DA-2004 is a four-dipole element array wide band VHF antenna for professional radio systems. Dipole incorporates “balun” matching circuit optimized for wide bandwidth and accurate matching. More gain is achieved by coupling single folded dipoles into arrays. Dipoles in array are coupled by precision phasing cable harness keeping low SWR and minimum insertion losses. The horizontal radiation pattern is adjusted by changing the distance between dipole elements and supporting mast. 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
DC grounded
for better lighting and
anti-static
protection.
