Specific Tower Setup Information
It is recommended that the receiver be, at minimum, 9.1
m (30 ft) away from the tower to prevent both Shading
and Multipathing. This distance may vary depending on
the frame design of the tower or structure that you are
mounting it around.
When using the 91 m (300 ft) extension harness, do not
cut the harness to the length needed. This harness has
built in voltage protection and is shielded. Cutting the
harness will limit the effectiveness of the harness and will
cause failures of either the radio or the receiver due to
static electricity build up on the harness. This harness
was built to be buried underground, so it is suggested to
bury all extra harness underground to protect the harness.
After deciding what structure that you will be mounting
your base station on, there are five different ways to set
up your base station.
• Utilizing Both The 91 m (300 ft) RTK Extension Harness
And Low Loss Coax Cable
• Utilizing The RTK Extension Harness
• Utilizing A Repeater
• Utilizing Just Low Loss Coax Cable
• Leaving The Radio And Receiver As A Single Unit
Utilizing The RTK Extension Harness
This base station setup allows you to mount the receiver
at a secure location and mounting the radio, with antenna,
to an elevated position, and utilizing 91 m (300 ft) of
RS232 cable between the receiver and radio.
