Description
In a GPS ground based receiver, a choke ring antenna can provide millimetre precision measurements for surveying and geological measurement applications. Surveyors use absolute locations to make maps and determine property boundaries. Our choke ring uses four concentric cylinders around a central antenna and manufacture with AS9100 compliant.
