Weak Signal Strength Environments
Many GPS installations require a very long cable between a rooftop-mounted GPS antenna and the receiver. In these situations a low-noise, inline GPS amplifier can make the crucial difference between your equipment operating properly or not. In many situations, multiple preamplifiers are needed and the wide supply voltage range and extremely low current consumption of our preamplifiers allows them to be cascaded over as long as 1000 feet using small diameter RG-59 type cable.
High Interference Environments
Interference rejection is crucial in GPS receiver applications. GPS antennas are often installed on rooftops with other communications antennas that are radiating interfering signals. The G-LNA2 preamplifier uses surface acoustic wave (SAW) filters and highly linear semiconductors to achieve very high interference rejection, even in the presence of high levels of interference.
