L1 Active GPS Antenna - L1A

GPS Antenna

The L1A is a high performance L1 GPS antenna that is ideally suited for many GPS applications requiring low noise and excellent gain. The L1A functions to specifications over the entire operational voltage and temperature range at a minimal current draw and includes high frequency selectivity to avoid interference with other nearby transmitters. The L1A is available with various common RF connectors. 

GPS Source has designed and manufactured all of their antennas for optimal performance at the voltage range stated. For example, antennas made by GPS Source that state they will work at 2.5V – 16V are designed to perform at 2.5V or 16V with optimal gain. GPS Source antennas designed to perform at 5V – 16V will have an optimal gain at 5V or 16V. GPS Source antennas work as expected at the stated voltage range with rigorous testing and data to ensure customer satisfaction.
