3. Approved Antennas
The antennas in Table 1 are tested and approved for use with the HUM-A-900-PRO Module. According
to the FCC Permissive Change Policy (178919 D01) “Additional antennas that are equivalent may be
substituted, and then marketed without a Class II permissive change… 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 grant of certification (FCC ID), and must have similar in-band and out-of-band
characteristics (consult specification sheet for cutoff frequencies). Contact Linx for information about
other antennas that meet these requirements and may be used with the HUM-A-900-PRO module.
