2-28 Chapter 2: Installing the Hardware Infrastructure
• On a suspended ceiling, mount the antennas to the ceiling tile. In an
open ceiling, hang the antennas from the roof trusses.
• When mounting the antenna, face the front of the antenna (the side
opposite the cable connector) towards the ESLs, with as few
obstructions between it and the ESLs as possible.
Caution: The transmit antenna is required to comply with FCC RF
exposure requirements for mobile transmitting devices. A separation of
20 cm (8 inches) or more must be maintained between the antenna and
all persons during device operation to satisfy RF exposure compliance.
Installing CBS Antennas
The transmit antenna and receive antenna kits include the same
mounting hardware. The installation procedures for the transmit and
receive antennas are the same.
Note: Observe the following precautions to avoid RX antenna ESD
failures:
1. Always connect the RX cable to the CBS before connecting the cable
to an RX antenna.
2. Keep antennas in their anti-static packing bags until they are ready
to be installed.
3. Before handling, installing, or removing an RX antenna, touch a
grounded metal surface.
4. Only trust antennas that arrive in silver-gray plastic bags with anti-
static warning stickers.
5. If using a lift truck, ensure that it has an anti-static ground drag
strap. If it does not, then drag a short length of metal chain from the
lift truck undercarriage to dissipate any static energy.
