9.2 Antennas
This microNode has been certified to operate with the antennas listed below. To adhere to
these certifications requires the antennas to be of the types specified below and of lower
gain. In all instances, the combinations of microNode maximum transmit power and antenna
gain must not exceed the regulatory Effective Isotropic Radiated Power (EIRP). Antennas that
are not of the specified type or are of greater gain are strictly prohibited for use with the
microNode, per On-Ramp Wireless’ EMC certifications. The required antenna impedance is 50
ohms.
