GPS RTK Base GPS Receiver User Guide 29

Setup Guidelines 4

The GPS antenna included with the AgGPS RTK Base 450/900 receiver

is a Trimble Zephyr Geodetic

™

Model 2 antenna. The Zephyr Geodetic

Model 2 antenna has a large ground plane to eliminate multipath and

can be used in both fixed (permanent) installations and mobile base

station applications.

Base station setup guidelines

For good performance, observe the following base station setup

guidelines:

• Place the GPS antenna in a location that has a clear line of sight

to the sky in all directions. Do not place the GPS antenna near

vertical obstructions such as buildings, deep cuttings, fences,

towers, or tree canopy.

• Mount the GPS antenna securely to minimize movement of the

antenna. Any movement of the base station GPS antenna will

cause corresponding movement in the rover.

• Place the GPS and radio antennas as high as practical. Radio

antenna height is a significant factor in the broadcast range of

the radio.

Note – The GPS antenna must have a clear line of sight to the sky at all

times during operation.

• Choose the most appropriate radio antenna for the desired

coverage area. The higher the gain on the antenna, the longer the

range. If there is more focus on the transmission signal, there is a

reduced coverage area. A 3 dB or 5 dB gain antenna provides a

mix of good range and reasonable directional coverage.
