of the antenna itself. Screw the bottom of the adapter onto a range pole, tribrach, tripod or
other equivalent mount. Attach coaxial cable from the antenna connector to the antenna
port on your receiver.
Caution:
Over tightening the metal adaptor into the plastic baseplate will damage
the baseplate.
The 600-LB antenna will allow you to achieve sub-meter accuracy in stand-alone
applications. It combines the advantage of dual GPS frequency performance and the
availability of differential GPS corrections from the OmniSTAR and other geo-stationary
satellites. Differential corrections coupled with the ability to know ionospheric
corrections will allow you to achieve sub-meter and even centimetre accuracy
without
the need to use ground based reference stations
