The 25316 Yagi antenna is used with the TX320, TX312, and OMNISAT-M satellite transmitters. This right-hand circular polarized (RHCP) antenna has 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. A COAXNTN-L cable is required to attach the antenna to the satellite transmitter.
Campbell Scientific's 25316 is a cross-Yagi antenna manufactured for our TX320, TX312, and SAT HDR GOES transmitters, and may also be used with some GOES transmitters manufactured by other companies. This high-gain, robust, lightweight antenna provides optimum performance for all fixed-location, Satellite Data Collection Platforms (DCPs). It consists of two quadrature-phased, five-element Yagi antennae, mounted on a common aluminum boom. The antenna’s screw-in elements facilitate shipping, storage, and fi eld installation.
Yagi antennas are a type of directional antenna that consists of a rod pointed in the direction of the transmission/reception and several cross bars oriented at a 90° angle to the main rod. The rods' length and spacing are optimized to transmit and receive transmission in the desired frequency band.
|Note: On March 10 2009 the 25316 11-dBi Yagi antenna replaced the 17751 11-dBi Yagi antenna. The 17751 antenna had replaced the 12261 9-dBi Yagi antenna on August 20, 2004.|
The 25316 Yagi antenna is used with the TX320, TX312, SAT HDR GOES, EUMETSAT, and OMNISAT-M satellite transmitters. It may also be used with some GOES transmitters manufactured by other companies.
The COAXNTN cable is used to attach the antenna to the transmitter.
