Advanced GPS Reception
概览
This GPS antenna is typically used with the TX326, TX325, and TX320 satellite transmitters or the AL200 ALERT modulator. This active GPS antenna provides 28 dBi of preamp for weak signal or long cable run applications. It also provides filtering to improve immunity to other RF signals, making it highly jam resistant. Its weatherproof package is designed to withstand exposure to shock, vibration, extreme temperatures, rain, snow, and sun. The antenna conveniently mounts to any 1 to 14" thread or 3/4" pipe thread, which includes the 30626 and 7623 mounts offered by Campbell Scientific.
