Orderable28 dBi 3.3 V active GPS Antenna without Cable
Overview
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.

Advanced GPS Reception
Technical Description
The 17992 is a 3.3 V active antenna. The voltage is supplied by the GPS receiver using the center pin of the coaxial cable, which is used to attach the antenna to the receiver. The power is used for active high gain preamp of the received signal and for RF filtering. The RF connector is type TNC (jack) and is located inside the threaded socket.

Orderable7623
3/4 IPS 10 in. Aluminum Pipe with Threads
An aluminum pipe is used to mount the GPS antenna to a crossarm. The pipe attaches to a crossarm via a 1049 NU-RAIL fitting or CM220 mount. The crossarm is then mounted to a tripod or tower.

3/4 x 1 in. Nu-Rail Crossover Fitting
The 7623 pipe mentioned above fits into this Nu-Rail Crossover Fitting. The fitting then attaches to one end of a CM202, CM204, or CM206 crossarm, and the crossarm mounts to a tripod or tower.
OrderableCM221
Right-Angle Mounting Kit
The CM221 mounts a pipe or tube at 90° to another pipe or tube. It is typically used to attach a sensor with a vertical pipe (including most wind sensors) to a crossarm. The cast aluminum, right-angle mounting bracket has 3.8 cm (1.5 in.) U-bolts and hardware and will accommodate tubing with a 1- to 1.5-in. outer diameter.
Orderable31326
Surge Protection Kit, GPS Antenna Type N to SMA
The 31326 is a GPS RF surge protection kit with flange mounting bracket. It may be flange-mounted to an enclosure backplate or bulkhead-mounted through an enclosure wall. One side of the surge protector connects to a GPS receiver with an SMA antenna connection. The other side connects to the GPS antenna/antenna coaxial cable with Type N connector. The surge protector passes up to ±6 Vdc, commonly needed for active GPS antenna applications.
