620, Omni-Directional ADS-B ANTENNA
Specifications
Performance Characteristics:
Type: Omni-directional
Azimuth Pattern: Circular to within ± 1 dB
Frequency Range: 978, 1030 & 1090 MHz (no adjustments or tuning required)
Array: 2 Dipoles and 2 Chokes in Vertical Plane
Polarization: Vertically Polarized
Gain, main beam: > 3 dBi
Gain, horizon: > 0 dBi
Main beam elevation location: Between 0° and +30° above horizon
Slope (Vicinity of horizon): 0.05 dB/°
Power Handling Capability: Up to at least 5 kW peak RF power at 3% duty cycle
Impedance: 50 ohm nominal
VSWR: Approxiamately 1:5:1 (1030 & 1090 MHz) measured at end of low loss cable not exceeding 5 feet in length.
Vertical Field Pattern: The radiation pattern of the antenna in the vertical plane has a lobe of energy not less than 15 degrees wide at the half-power points. The power gain at angles between 30 and 90 degrees below the horizon shall be lower than the power gain at the peak of the major lobe above the horizon by at least 12 dB. The power gain at angles between 6 and 40 degrees above the horizon shall not pass under a straight line joining the points of co-ordinates (+6°, -15 dB) and (+40°, -25 dB) with values referenced to the peak of the major lobe above the horizon.
Size: 24" tall, 2 radiator assemblies (driven elements) plus a choke assembly at each end, 3 1/4" OD radome.
Weight: 6 lbs.
Physical Design: A metal tube, 1.5" OD x 1.43" ID (.040" wall thickness) runs through center of antenna for full length. RF transmission line assembly is located within this tube.
Weather Proofing: Entire Antenna, including all cable connectors is weather proofed such that removal /replacement of radome is possible without sealing compounds.
Antenna Mounting: The configuration of the antenna base is such that the antenna can be mounted directly to a 1.5” diameter vertical pipe (1.5” pipe has a nominal OD of 1.90”). Pipe Sleeve overlaps mounting pipe by 5”. Two 3/8” Bolts secure antenna to mounting pipe.
Wind Loading: Withstands without damage 100 mile per hour gusts.
Monitor Ports: Not supported - contact factory if required.
Obstruction Light(s): Not supported - contact factory if required
Connectors RF: Type N female 1 each.
Environmental: - Meets FAA-G-2100c Environment III.
- Temperature, -50 to +70 degrees C
- Humidity, 5 to 100%
- Altitude, 0 to 10,000 Feet ASL
- Ice Loading, 1/2" Radial Ice.
