4.3 Antenna configurations
Antenna alignment and antenna spacing with an external antenna
The minimum distance required between antennas that use the same frequency and that are
connected to different readers depends on the set maximum radiated power and the antenna
alignment.
Maximum radiated power of the antennas:
● RF620R/RF630R = 500 mW ERP
● RF620R/RF630R with RF660A = 2000 mW ERP
● RF640R/RF670R with RF660A = 2000 mW ERP
● RF650R with RF660A = 1000 mW ERP
● RF680R with RF660A = 2000 mW ERP
● RF685R = 2000 mW ERP
● RF685R with RF660A = 2000 mW ERP
