5700 Operation
2.7.3 Antennas
The 5700 receiver should normally be used with a Zephyr or Zephyr
Geodetic antenna. These antennas have been designed specifically for
use with the 5700 receiver.
Use Figure 2.15 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 2.14 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. If you want to use one of these antennas with a 5700
receiver, then you need to use an antenna power adapter, available
from Trimble, and an external power source for the antenna.
