200A-IMLA GPS ANTENNA, INTEGRATED MULTIPATH LIMITING
The dBs 200A-IMLA consists of two antennas coaxially mounted (1.ea. MLA & 1 ea. HZA). The MLA is for tracking of SV's near the horizon (<3°) up to an elevation angle of 35° and the HZA tracks SV's above 30°.
The MLA is a very high gain (> 8 dBi) omni-directional GPS ground station antenna comprised of 16 wide aperture colinear dipoles.
Several IMLA's are used (two to four) at each LAAS ground station in the National Airspace System (NAS).
The IMLA is also well suited for other GPS based systems which require high levels of GPS multipath rejection, interference rejection, and high GPS signal-to-noise ratio.
The dBs 200A MLA antenna is vertically polarized and is specifically designed to operate with GPS signals operating at 1575.42 MHz ± 20 MHz.
The dBs 200A-HZA is Right-Hand-Circularly-Polarized to maximize the received signal emitted from the GPS satellites. The dBs 200A-HZA is specifically designed to operate with GPS signals operating at 1575.42 ± 10 MHz.
Each of these two antennas have their own output connector which connect to separate GPS receiver inputs.
