GOES Crossed Yagi Antenna
GOES Crossed Yagi Antenna is a lightweight, all-weather antenna
designed to operate in the 401 to 402 MHz frequency range. This
antenna radiates right-hand circular polarized energy in a pencil beam
pattern with a beam width of approximately 45 degrees measured at the
half-power points. The input impedance is 50 ohms, and the VSWR
across the operating frequency range of the antenna is better than 2:1.
Antenna gain is approximately 10 dB and is designed to provide
optimum signal levels at the GOES satellite when connected to the
10 W GOES radio transmitter. The antenna is designed to be
conveniently disassembled for transport.
