2.3.4 Ceiling Installation of Readers and Antennas
The following steps describe how to connect a Reader to an Antenna and install the assembly into the
ceiling. Start by installing the first Reader in the chain from the SDP, and proceed down the chain to
the last Reader. This will allow Readers to be powered and their operation verified as they are installed.
2.3.4.1 Mounting Readers to Antennas
1) Place the Antenna panel dome-side down on a flat surface, and place the Reader on the Antenna
panel. Align the four screw slots in the reader flanges with the
holes in the Antenna panel.
2) Connect the Reader SMA port to the Antenna SMA port using
the provided coaxial cable. Hand-tighten the SMA
connections.
3) Screw the reader to the Antenna panel using the screws
provided in the Antenna kit.
4) Tighten the SMA connectors to 3-5 in-lbs using a 5/16"
wrench. Do not over-tighten the SMA connectors.

2.3.4.2 Installing Reader / Hinged Antenna
Assemblies
1. Remove the existing ceiling tile and any insulation batts above
the tile. Do not re-install insulation after the Antenna is
mounted.
2. NOTE: If a 2' x 4' tile is being replaced, a cross tie (not
included) may be added for improved cosmetic appearance
for the ceiling tile; the PLUS antenna is rigid enough that it
does not need a cross tie for support.

and Drop Panel
3. Prior to inserting the Antenna frame into the ceiling, rotate the
frame so that the notches at the corners of the frame are
oriented to the left and right rear sides of the frame.
4. Tilt the Antenna frame and insert it into the ceiling opening.
Lower the frame so that it is seated evenly on the drop ceiling
cross-ties.
