Tabletop Point-of-Sale (POS)
For Point-of-Sale (POS) installations, the Times-7 RFID Near-Field Antenna A1030 is
recommended. The A1030 antenna offers outstanding near field performance in a unique
and optimized footprint, improving workflow and eliminating stray tag reads. These
antennas have a circularly polarized pattern and have -15.0 dBi gain.

Proper RF Cable Type
The type and length of coax cable can greatly affect the tag read performance of the
installation. RF performance (aka read range) is determined by a combination of transmit
power, receive sensitivity, cable losses, antenna gain and tag type. For a given RFID
reader and tag, the variables to consider during installation are cable losses and antenna
gain. The longer the cable, the greater the loss. If longer coax cable runs are required, a
larger diameter, lower loss cable type should be used to mitigate the losses due to the
increased length. Table 4 Cable Loss Chart is provided for common coax cables used for
RFID installations
