Antennas
The Trimble R7 receiver should normally be used with a Zephyr or
Zephyr Geodetic antenna. These antennas have been designed
specifically for use with the Trimble R7.
Use Figure 3.14 as a guide for measuring the height of the Zephyr and
Zephyr Geodetic antennas. The Zephyr antenna is designed to be
measured to the top of the notch. The Zephyr Geodetic (shown) has
been designed to be measured to the bottom of the notch.
Figure 3.14 Measuring antenna height
Older models of antennas, such as the Choke Ring or
Micro-Centered™ L1/L2 antennas, need more power to operate than
the Zephyr models. To configure the receiver to output more power on
the antenna port, select the correct antenna type in GPS Configurator,
or through the Trimble controller. For information on how to do this,
contact your local Trimble Service Provider.
