Things to Consider
IMPORTANT!
The Reader must be installed in a moisture-free
environment at approximately room temperature and a minimum of
36 inches above the floor. Installation at eye height is recommended.
If possible, position the Reader and the ATU where they are not
readily accessible to help prevent tampering or accidental damage.
Cabling
•
Use only RG-58/U coaxial cable with 50-ohm impedance
(nominal), solid copper center conductor, 55% tinned copper
braid or better, 100% foil shield coverage (for example, Belden
9310).
•
The maximum recommended cable length between the Reader
and ATU is 80 feet.
•
The maximum recommended cable length between the ATU and
the antennas is 20 feet.

or if the cable is kinked.
