2.4.3 External RF cable description
Picture 2-10 RF cable schematic chart
The connector between RF cable & reader is TNC male, the connector between RF cable
& antenna is SMA male connector (depending on antenna connector as well). Try to keep
the cable length within 5meters, impedance 50Ω, the insertion loss less than 2dB. Of course,
you can choose a high-performance cable, appropriately increase the length, but keep the
insertion loss less than 2dB.
Note: Too long RF cable or cable poor connection will cause high signal attenuation & poor
reader performance.
2.4.4 External antenna description (optional)
This reader has a integrated circular antenna. User can also connect one more external
antenna. It is recommended to use the external antenna provided by our company.
