Measure the ATA tag footprint.
Pay close attention to the point of the first read. You may find that the first read
point for the ATA tag differs from the first read point of the IT2235 Tag. If this
difference is undesirable, you can adjust the ATA tag range independent of the
IT2235 Tag read range by changing the uplink attenuation. ATA tags respond to
uplink RF power only; the IT2235 Tag response is relatively independent of
uplink power.

Once the ATA and IT2235 footprints have been matched to a satisfactory degree,
recheck the IT2235 Tag footprint to ensure that the ATA adjustments have not
adversely affected the IT2235 footprint.
