Installation of the RTK radio and antenna
After installing the base station receiver, installing the
radio in a location to best maximize the output can be
a challenge. Below are four options currently available
through John Deere.
• Leave the RTK radio in its original configuration
attached directly behind the base station receiver.
- Use a repeater as part of the base station. Install a
radio with the base station receiver.
- Install a Repeater radio (available through whole
goods or parts) in an elevated location.
• The base station will then send the RTK data to the
repeater and the repeater will then transmit that data
out to the repeater , and vehicle on the network. This
will eliminate other repeaters in the system.
NOTE: Additional repeaters cannot be run off of the
central repeater. In areas with heavy foliage or
uneven terrain, this setup method is not advised.
• Use 92 m (300 ft) extension harness PF80821 to move
the radio from the back of the base station receiver to
an elevated position.
NOTE: Use extension harness PF80821.
Use installation instructions provided with
extension harness PF80821 to ensure proper
grounding and wiring according to the installation
instructions. This harness has built in protection
for both the radio and receiver for unwanted static
electricity developed on the harness.
• Attach the RTK radio in a safe and unobstructed
location, Connect radio and antenna using coaxial cable.
IMPORTANT: The antenna must be installed before
the radio module is powered ON.
Avoid water intrusion by keeping the antenna
attached to the radio whenever possible.
Removing the antenna while transmitting
may damage the radio module.
IMPORTANT: If using a coaxial cable between the
radio and antenna, use the lowest-loss cable
available to avoid RTK radio link range issues.
NOTE: When using this option, it may be
necessary to install a higher-gain antenna
to compensate for loss.
NOTE: Old antennas from past receivers are not
compatible with the StarFire 3000 receiver.
Always mount the radio antenna vertically to make sure
that the RTK signal is radiating outwards. If the antenna is
at an angle, it may cause the data received at the vehicle
to be lower than expected.
