3 INTRODUCTION
This manual contains installation procedures for the Unity XG-100M mobile radio, the CH-100 and
CH-721 control heads used with the radio, and related equipment. Procedures cover the mounting and
cabling of the equipment, as well as basic in-vehicle performance test procedures. In addition, important
product safety-related information is included.
3.1 GENERAL DESCRIPTION
The Unity XG-100M mobile radio is a high-performance multiband mobile radio with advanced
capabilities and unprecedented interoperability capability. The radio supports P25 trunked, P25
conventional, and analog conventional operations. It covers the 136 to 174 MHz VHF band, the 380 to
520 MHz UHF bands, and the 762 to 870 MHz bands. In the future, the radio will also cover the 30 to
50 MHz VHF-low band with the addition of an external RF power amplifier.
The Unity XG-100M mobile radio and related equipment are designed to operate in a mobile
environment, typically within a motor vehicle. The radio must be connected to an external vehicle-
mounted transmit/receive antenna system approved for use with the radio. Several different types of
antenna mounts and a multiband antenna element are approved and available for use with the radio. This
antenna element and the mounts are listed in Table 1-1 on page 8 and in Table 4-7 on page 30.
When operating on a VHF or UHF radio channel, the Unity XG-100M radio can provide 50 watts of
transmit output power in full-power transmit mode. When operating on a 700 or 800 MHz radio channel,
the radio can provide 35 watts of power in full-power transmit mode. As of the publication of this manual,
regulatory certification limits transmitter power to 26.3 watts in the 700 MHz band.
Front-mount and remote-mount radio configurations are available. In the front-mount configuration, the
control head is an integral part of the mobile radio. In the remote-mount configuration, the control head is
located near the radio operator’s position and the radio is mounted remotely from the control head,
typically in the vehicle’s trunk or on an equipment shelf. Three (3) different control heads are available
for use with the radio. All three are available in both a remote-mount and a front-mount configuration:
• CH-100 Control Head—Shown in Figure 3-1 below in a front-mount radio configuration, the
CH-100 features a 4.3-inch touchscreen sunlight-readable LCD color display, providing an easy-to-
use menu-driven operator interface. This head also features a Bluetooth wireless interface for
connection of optional equipment and to support radio and control head programming via a wireless
connection. The front panel of the CH-100 head also features an easy-to-use on/off/volume control
and group/channel selection controls, an emergency button, a home button, a USB programming port,
