DAB-ARYCKM-D-48X 4-Element Directional Yagi Antenna
The DAB-ARYCKM-D-48X is a professional 4-element directional Yagi antenna designed for DAB broadcast transmission within VHF Band III from 174 to 240 MHz.
Each antenna is factory tuned to the required DAB block within the 174–240 MHz range and provides an operating bandwidth of 20 MHz. The directional radiation pattern, maximum gain of 10.2 dBi and controlled beamwidths provide focused coverage and efficient use of the transmitted RF power.
The DAB-ARYCKM-D-48X is suitable for professional broadcast sites, directional coverage systems and collinear arrays composed of multiple antennas. It can be installed in vertical or horizontal polarization according to the required radiation configuration.
The boom and support structure are manufactured in stainless steel. The radiating dipole and elements are available in anticorodal aluminium or stainless steel. All metallic parts are electrically connected to ground in a DC-grounded configuration.
An optional PVC radome protects the matching section against snow, ice, salt and severe atmospheric conditions. Versions with N-female or 7/16-female connector are available for power levels up to 500 W or 1,000 W.
