610-D/10 DME ANTENNA, UNI-DIRECTIONAL
Specifications
Performance Characteristics:
Type: Uni-directional
Circularity (Azimuth Pattern): 90° Nominal HPBW
Frequency Range: 960 through 1215 MHz (no adjustments or tuning required)
Array: 4 radiator assy's (35" tall)
Coaxial Cable: Semi-Rigid, Low Loss, Phase Stable
Polarization: Vertically Polarized
Gain, main beam: > 9 dB/iso, minimum
Gain, horizon: > 7 dB/iso, minimum
Main beam elevation location: 10° nominal above horizon
Slope (Vicinity of horizon): 0.35 dB/° nominal
Power Handling Capability: Up to at least 5 kW peak RF power at 3% duty cycle
Impedance: 50 ohm nominal
VSWR: not greater than 2.5:1 (960-1215 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 20 degrees wide at the half-power points. The power gain at angles between 10 and 50 degrees below the horizon shall be lower than the power gain at the peak of the major lobe above the horizon by at least 8 dB. The power gain at angles between 6 and 30 degrees above the horizon shall not pass under a straight line joining the points of co-ordinates (+6°, -15 dB) and (+30°, -25 dB) with values referenced to the peak of the major lobe above the horizon.
Size: 36" long, 4 radiator assemblies (driven elements), 6 1/4" OD radome. Has top cap and base flange.
Weight: 21 lbs. (excluding obstruction light and mounting fixtures and other optional items).
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 and obstruction light power lines are located within this tube. Also used as lightning down conductor.
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 or indirectly through use of optional adapter(s).
Temperature: Operational Temperature Range -50 degrees C to +70 degrees C.
Wind Loading: Withstands without damage 100 mile per hour gusts
Monitor Ports: Optional coupling ports for monitoring the signal radiated by the antenna. Located within the radome can be provided as optional items. 50 ohm nominal impedance. Probe output level is 25 dB ± 1.5 dB (for J2 and J3) below power level applied to main RF input connector.
Obstruction Light(s): Optional dual, red lamp obstruction light fixture. Connector is MS-3112E8-3P, 13 1/2'H x 12"W x 4"D 5.3 lbs.
Connectors RF: Type N Female. 2 each for optional monitor ports.
Pipe Adapter: Solid cast aluminum part (A356-T6). Painted white. Adapts 4" OD pipe to antenna base. 12"H x 8" greatest dia., 8.3lbs., excluding cover, stainless steel cover weight 1.5 lbs.
