We strongly recommend against using a rigid helical antenna configuration as shown below. The RTK Surveyor is
not designed for such configurations and can lead to permanent damage to the antenna connector. The helical
antenna becomes a large lever arm. If the unit is dropped this lever is capable of damaging both the SMA
connector and where the connector is soldered to the PCB.
Dangerous Antenna Configuration
If you’re shopping for a cell phone clamp be sure to get one that is compatible with the diameter of your monopole
and has a knob to increase clamp pressure. Our monopole is 27mm in diameter and we’ve had a good experience
with this clamp and this clamp. Your mileage may vary.
If you are receiving RTCM correction data over a radio link it’s recommended that you attach a radio to the back of
the RTK Surveyor.
