Tallysman’s wideband GNSS TW4320/TW4322 antenna is designed to cover the L1 GLONASS, L1 GPS, and SBAS (including EGNOS/MSAS/WAAS) frequency bands (1575 to 1606 MHz). Unlike conventional antennas, its small patch element provides 50 percent wider bandwidth. The unit excels over competition, because the 1dB power received bandwidth includes both GLONASS and L1 GPS signals.
Its two-stage low-noise amplifier has a mid-section SAW. The TW4322 can be obtained with a constricted pre-filter which guards against the undesirable saturation coming from L-Band signals and high-level sub-harmonics. The IP67 plastic enclosure comes with a magnetic mount. A cable 3 meters long and several connectors are included in the package.
A tight pre-filter is included in the TW4322 to protect against saturation by high level sub-harmonics and L-Band signals.
Applications include military, covert surveillance, security, cost-sensitive positioning asset tracking and fleet management.
