John Deere RTK Radio 900

Base stations using John Deere RTK Radio 900 are very easy to set up for several reasons:

Licensing

The John Deere RTK Radio 900 operates in the 902-MHz to 928-MHz frequency range. This range does not require a license from the U.S. Federal Communications Commission (FCC), so the base station can be set up anywhere as long as it does not broadcast more than 4 W of power.
 
For more information on FCC regulations of the 902-MHz to 928-MHz range, visit www.fcc.gov or talk to C&B Operations.

Mounting

Mobile base station configuration

Permanent base station configuration

A John Deere RTK Radio 900 base station can be used in a mobile setup or mounted permanently to a building, concrete silo, or radio tower. Depending on the operation, either type of mounting can be used:

• Mobile base station
  • Fields are spread out and one base station cannot cover all of the ground
  • For producers in areas with hilly terrain and lots of foliage where a permanent base station would not provide adequate coverage
  • Situations where accuracy is needed, but not repeatability
• Permanent base station
  • Producers in areas with flat terrain and little foliage where a permanent base station would provide adequate coverage in a large region
  • Multiple tractors in different fields could use the same base station instead of purchasing a second one
  • Situations where accuracy and repeatability are needed

Repeaters

If a producer using RTK discovers a signal hole where the signal is lacking, a repeater radio can be easily set up to help fill the gap.

Broaden RTK availability with repeaters

RTK repeaters are radios that can be used to improve base station signal coverage around obstacles, such as trees or rolling terrain. The purpose of the RTK repeater is to receive the correction signal coming from the base station and then transmit that correction signal.

More than one repeater can be used with one base station, but the repeater cannot receive signal from each other in a daisy-chain configuration. In order to operate, a repeater must be connected to a 12-V power source.

A repeater is the same as the radio that is on a machine or base station receiver.

A repeater consists of the following:

• John Deere RTK Radio 450 or 900
• Power harness and bracket
