The StarFire™ receiver provides a great deal of accuracy (3 cm [1.2 in.]) when used as a standalone unit. If you find yourself in a situation where you need a greater level of accuracy or if you need precise vertical accuracy, a StarFire receiver paired with a John Deere RTK Radio may be the solution for you.
More than 200 John Deere dealers across the United States and Canada have set up a large, robust RTK network. This is beneficial for several reasons:

A U.S. Federal Communications Commission (FCC) license is required when utilizing the John Deere RTK Radio 450 on a base station or as a repeater.
Licensing is not required for an RTK machine configuration.
For more details and assistance on obtaining a license, refer to the Dealer Corner section of StellarSupport™ system.
The John Deere RTK Radio 450 requires a license for a dedicated frequency. While a license must be paid for, the user owns that specific frequency. Unlike the John Deere RTK Radio 900 frequencies, wireless providers or anyone else cannot use that frequency, thus eliminating signal jamming.
The following is a simple way to think about the difference between a John Deere RTK Radio 900 and RTK Radio 450:
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:
