The RI-ANT-G01E, RI-ANT-G02E antennas have 1m tails and are nominally 27 µH
and when connected to the appropriate RF Module can be tuned to resonate at 134.2
kHz. The RI-ANT-G04C antenna is provided with no tail and is nominally 26 µH. If
2.5 mm
2
(14 SWG) wire is used, a 4m (12’) tail can be added and still be capable of
being tuned to resonance.
Information:
The antenna tail is an integral part of the RF Module’s matching
circuit. Changing the length of the tail changes the performance.

The MicroReader requires an antenna with a self inductance of 47 µH. The following
antenna is available:
