DESCRIPTION
These antenna products connect to Radio Frequency Modules (RFM) and reader/writers to form the interface to
the low frequency (LF) 134.2 kHz Texas Instruments transponders. In combination with a reader/writer they
transmit energy and signals to the transponder and receive the response from the tag. There are three standard
gate antennas (small, medium and large), two standard stick antennas with 1 or 3 meter cable length and a stick
antenna specially designed for use with the Mini-RFM available for usage in low frequency systems. Each
antenna is capable of creating a specific size and shape of read zone to meet the requirements of the target
application. In general the gate antennas create a large read zone including greater read distance, while the
stick antennas provide a more focused read zone and an ability to discriminate between transponders.
The antennas are well suited for usage in a broad range of applications including, but not limited to, access
control, vehicle identification, container tracking, asset management and waste management applications.
