According to FCC KDB 178919 [5] 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).’
