•
The optimum operating Q factor of the antenna should be in a range of QB = 10...20. To
determine the operating Q the antenna must be supplied with a 50 Ohm source such as
a network analyzer or frequency generator.
•
When connecting an antenna, ensure that it does not exceed the permissible limits pre-
scribed by the national regulations for radio frequency devices.
Installation with FCC Approval:
In countries where FCC approval is required, the ID ISC.MR100 Reader may only be operated
using the antennas listed in Table 7. Changes or modifications not expressly authorized by the
relevant approval body may result in revocation of the user’s operating permission.
