The 25316 is a Right-Hand Circular Polarized (RHCP) Yagi antenna with a gain of 11.0 dBi. The 25316 must be "aimed" at the proper azimuth and inclination to "hit" the satellite. An adjustable mounting bracket is included.
The COAXNTN-L is an RG8/U, low-loss, coaxial cable with a characteristic impedence of 50 ohms. It has two Type N male connectors for attaching the TX312 transmitter to the antenna.
This 10 ft (3.1 m) roll of 1"-wide black self-vulcanizing tape can help protect the GOES antenna connection. After connecting the coaxial cable to the antenna, wrap the tape around the connectors that are exposed to the environment.
The 17992 GPS antenna is both jam resistant and submersible for greater reliability under field conditions. It requires a 18017 antenna cable and mounting hardware (7623 pipe, CM202-series crossarm, and CM220 or NU-RAIL connector).
The 18017 cable connects the 17992 GPS Antenna to the TX312. The cable has a TNC connector on one end and an SMA connector on the other end. This cable is required if the 17992 is ordered.
For use with the 17992. 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.
An aluminum pipe is used to mount the GPS antenna to a tripod or tower. 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.
The 7623 pipe fits into this NU-RAIL fitting. The fitting then attaches to one end of a CM202, CM204, or CM206 crossarm, and the crossarm mounts to a tripod or tower.
The 31324 is a GPS RF surge protection kit that is installed by Campbell Scientific, bulkhead-mounted through the 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.
