System Technical Specifications
C-7
• Weatherproof—Each antenna is housed in a radome made of materials with favor-
able electrical characteristics and resistance to ultraviolet radiation.
• Bandpass filtering helps to attenuate interference from other RF sources.
Environmental Specifications
The AA3152 and AA3153 antennas can withstand the environmental tolerances
shown in Table C-8.

IT2502 Check Tag Antenna
The IT2502 Check Tag Antenna allows the reader logic card and RF module to test
system operation using the check tag. The check tag antenna is mounted near the
transmit antenna and connected to the RF module through a low-loss, coaxial RF
cable.
