2.4.3 Feeding line(optional)
Image 2-6 schematic diagram of feeder line
RF cable TNC(Reverse polarity, internal thread, inner pin) connector connect with
reader antenna TNC connector, RF cable SMA connector connect with external circular
polarization antennas SMA connector, cable maximum length is 5m, impedance 50Ω,
insertion loss is less than 2dB, or you also can choose a high performance cable,
appropriate increase in length, insertion loss is less than 2dB.
Note: If Ultra long RF cable or the cable joint is not contacted well, may cause
performance deterioration on the read and write because of the emission signal and the
received echo signal’s attenuation.

Network interface used for long-distance high-speed connection (less than 80 m), can be
connected with the switcher or router through the network cable, or directly connected
