5 Antenna Installation
To send and receive data to and from the tags an appropriate HF RFID antenna (13.56 MHz,
50 Ohm) has to be connected to the reader. This is done via the BNC connector on the
reader.
To connect the antenna to the reader or multiplexer the devices are equipped with BNC
jacks and the cables are equipped with BNC plugs at both ends. When connecting antennas
with multiplexers or readers please keep in mind that the cable has a signal dampening
effect reducing the RF power reaching the antenna. If long cables are to be used in
connection with one or more multiplexers the reading range can be reduced measurably.
Using higher quality cables can reduce the power loss in cases in which this is important.
Recommended cables with different lengths can be ordered from metraTec as accessories.
ATTENTION
Always connect a 50 Ohm antenna as described above first, before powering
the device. Powering the reader without an appropriate 50 Ohm load for a
longer time could damage the reader permanently.
5.1 FCC / ISED Compliance / Professional Installation
Installing a correct RFID system is a complex task. Besides a safe electrical installation it is
also import to install the antenna in a correct manner to ensure nominal operation. The
system can be influenced by the environment surrounding the antenna, the cables used as
well as other devices in the vicinity of the system. Therefore, this system should only be
installed by professional installers that have the necessary equipment to make sure the
reader and antenna work as intended.
Only the following antennas are approved to be used with the QuasarLR by the FCC
according to FCC Part 15 and ISED Canada according to RS210:
