13.1.3 Approved Antennas

To maintain modular approval in the United States, only the antenna types that were tested shall be used. Testing of the ATSAMR30M18A module was performed with the antenna types listed in Table 11-1.

According to KDB 178919 (Policy), it is allowed to substitute approved antennas through equivalent antennas of the same type with equal or less antenna gain:

‘Equivalent antennas must be of the same type (e.g., yagi, dish, etc.), must be of equal or less gain than an antenna previously authorized under the same FCC ID, and must have similar in band and out-of-band characteristics (consult specification sheet for cutoff frequencies).’
