L1 Active GPS Antenna - L1A
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.
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.
