Installing the Antenna
UltraVoice Remote Interface (UVRI-B)
Installing the Antenna
Determine type of antenna to be installed if a wireless RF system is used:
• Cabinet Mounted Magnetic Base
• Remote Mounted Magnetic Base
• Yagi External Antenna Type
• Omni external antenna Type
Installing the Cabinet Mounted Magnetic Base Antenna
If the UVRI-B is being installed in a very good RF coverage area, you may use a cabinet
mounted magnetic base antenna.
1. Connect the antenna cable to the antenna connector on the top of the UVRI-B
cabinet.
2. Mount the magnetic antenna base on the top of the UVRI-B cabinet.
Installing the Remote Mounted Magnetic Base Antenna
The remote magnetic base antenna allows for additional antenna height to improve
reception.
1. Locate a suitable location for the antenna that is away from any electrical devices,
high voltage and computer wiring. Locate as high as possible to enable the antenna
mast to be at least 2 feet away from any grounded metal objects.
2. Mount the antenna to a flat, secure metal structure with at least 225 inches square
area that the magnetic mount will securely stick to.
Installing the Yagi Antenna
Yagi Antenna Pre-Assembly Instruction
To pre-assemble the antenna, do the following:
1. Unpack the antenna and locate the following parts:
• Boom (1-14 inches for 5 element model, 7/8 inch-diameter for 3 element model)
• 3/8 diameter elements (y---3 = 3 elements, y----5 = 5 elements)
• Gamma match parts bag
• Mounting bracket parts bag
2. Find the proper element dimension chart for your antenna, within the antenna
instructions, and trim each element according to your operating frequency. Use care
to trim equal lengths from each end of each element ensuring that the mounting hole
is at the center.
