The Tallysman anti-jam feature modifies the radiation pattern of the GNSS antenna such that signals arriving from 10° below and 15° above the horizon are attenuated by 20 dB, while the gain at zenith is increased by 2 dB. Since jamming signals typically originate at low elevations, the TW3752AJ antenna mitigates inteference signals below 15°. Calian's patented Accutenna® technology enables the TW3742AJ antenna to provide a truly circular right-hand polarized signal through the entire bandwidth, thereby enabling superior multipath signal rejection and out-of-band signal rejection. This feature makes the TW3742AJ ideal for professional precision timing and positioning applications. The TW3742AJ features a precision-tuned, dual-feed patch element. The signals from the two orthogonal feeds are combined in a hybrid combiner, amplified in a wideband LNA, then band-split for narrow filtering and further amplified before recombination at the output. The antenna also has a strong pre-filter to mitigate inter-modulated signal interference from LTE and other cellular bands. The TW3742AJ offers an excellent axial ratio and a tightly grouped phase centre variation. The TW3742AJ is housed in a permanent-mount metal base with two nickel-coated nuts and an IP67 weather-proof enclosure. Two mounting options are available: an L-bracket (P/N 23-0040-0); or a pipe mount (P/N 23-0065-0). ## Applications - High-accuracy & mission-critical global positioning - Timing applications - Law enforcement and public safety ## Features - Accutenna® technology - Great axial ratio (2.0 dB typ.) - Low LNA noise (3.0 dB typ.) - High-rejection SAW filter - High-gain LNA (40 dB typ.) - Low current (19 mA typ.) - Wide voltage input range (2.5 to 12 VDC) - ESD circuit protection (15 kV) ## Benefits - Operates under ground-based jamming • Circular polarisation throughout the full bandwidth - Superior multipath signal rejection - Excellent signal-to-noise ratio - Excellent out-of-band signal rejection - Increased system accuracy - Ideal for harsh environments - IP67 weather-proof housing - RoHS and REACH compliant About Calian: With global headquarters and manufacturing in Ottawa, Canada, Calian is a leading manufacturer of highprecision antennas and components for Global Navigation Satellite System (GNSS) applications.
