CR2000 - Antenna mounting
The antenna will be mounted over-head at a height of Ha ft
with horizontal polarization where Ha is measured from the
highest part of the antenna. Determine the distance Do (in ft)
between the "pick-up point" and the antenna mast, and use it
to determine the antenna tilt down angle α° in the in-lane
direction (H Plane), using the following table.

* Distance referred to the antenna mast.
** Based on semi-empirical data.
Note: User must maintain a separation distance of 23cm from
the antenna. The antenna has gain of 6 db.
CR2000 - Installation Steps
Connect the antenna with the reader via RF feedline and RF
attenuator(s) and antenna adapter cable.
1) Disconnect the power main input to the power supply.
2) Connect the Power supply output to the CR2000 reader.
3) Connect the PC port COM1 to the reader host port using
the provided straight through RS-232 cable.
4) Connect the RF cable adapter (RG58 short cable) to the
reader RF port (Type N connector).
5) Connect the RF feedline to the RF cable adapter via the
fixed attenuator(s) referenced in step 9. Install a Type-N
Male connector at the end of the feedline.
6) Route the RF feedline through the wall. At the feedline
antenna end, slip 6" of heatshrink tubing on the cable.
Install a Type-N female connector at the end of the
feedline. Make the connection with the antenna.
7) Reconnect the power main input to the power supply.
8) Execute the CR2000 PC application software as
referenced in document A316000-743.
9) Determine the "total RF attenuation" value by varying the
configuration of the available fixed attenuator value(s).
10) After the system has been fully tested OK then heat shrink
the tubing (in step 6) over the antenna connector to make
it water tight.
