Model 50270s
270 MHz Antenna
The Model 50270s antenna has greatly improved resolution performance over previous GSSI
mid-frequency antennas, such as the Model 3105 (300 MHz). The Model 50270s incorporates
GSSI’s Smart Antenna recognition technology and will identify itself to select GSSI control
unites. The Model 50270s can be used in continuous, survey wheel or static stacking modes.
The Model 50270s has a center frequency of 270 MHz when measured in air.
