5 INTRODUCTION
This manual contains procedures for installing the XL Mobile radio, the Control Head, and related
equipment. Procedures cover the mounting and cabling of the equipment in front-mount or remote-mount
configurations and basic in-vehicle performance testing.
5.1 GENERAL DESCRIPTION
The XL Series mobile radio provides the advanced connectivity that first responders require, while
addressing evolving voice and data communications. It meets MIL-STD-810G for durability. XL Mobile
radios support P25 Trunking, P25 Conventional, Enhanced Digital Access Communications System
(EDACS), analog conventional, and BeOn
®
operation over a Wi-Fi
®
or LTE network.
The XL Mobile is a P25 converged, multiband Land Mobile Radio with an option to include LTE
(optional). Designed for anyone who needs to communicate with multiple agencies or across multiple
bands, the XL Mobile delivers mission-critical connectivity.
The XL Mobile radio and related equipment are designed to typically operate in 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. The antenna elements and mounts are listed in Table 1-1.
The XL Mobile installation includes a Control Head and the Vehicular Communications Hub (VCH),
which are described in the following sections.
5.1.1 Vehicular Communications Hub (VCH)
The XL Vehicular Communications Hub (VCH) is the main radio unit in a vehicular (mobile) radio
system. A major feature of the VCH design is the use of IP networks for tethering multiple radio Control
Heads.
