The dBs 620-D, Variable Beamwidth, is a 2 element high performance, full service, omni-directional, Automatic Dependent Surveillance-Broadcast (ADS-B) antenna. Frequency range is 978, 1030, and 1090 MHz (no adjustments or tuning required).
This omni-directional antenna has 2 active elements and other components, which produce high main lobe and horizon gain. Gain, main beam from 13.2 dB/iso min HPBW (35°) to 6.8 dB/iso at max HPBW (210°). Gain, horizon 2 dB down from main beam peak gain. The main lobe of the vertical pattern has been squinted to 10° above the horizon for improved multipath performance. The main lobe of the vertical pattern can be adjusted between 0° and +30° above the horizon upon request.
The antenna is lightweight, small, and 100% metal tubular construction making it extremely rugged.
The main RF input connector uses a Type N jack.
The model dBs 620-D Variable Beamwidth ADS-B antenna has been designed for ruggedness, lightweight, minimum size, long life, and in accordance with FAA-E-2754 and FAA-E-2100. It also exceeds the requirements of the UK CAA specification.
