13.2.2 Antenna Choices – 4.9 GHz
The integrated antenna has a gain of 22dBi.
In FCC/Industry Canada regions when using antennas with >26 dBi of gain it is necessary to
turn down the TX Power by the number of dB that 26 dBi has been exceeded.
13.2.3 Antenna Choices – 5.8 GHz
The integrated antenna has a gain of 23.5 dBi.
In non-FCC regions antenna choice is not restricted but any region specific EIRP limit should
be obeyed, see Table 7 in section 5.2 “Region Codes”
In FCC regions external antennas from the list in Section 13.7 “Antennas for 5.8GHz FCC
Regions” can be used with the Connectorized version of the PTP 400 Series bridge. These
are approved by the FCC for use with the product and are basically constrained by the
following limits:
• Single Polarization Flat Plate Antennas – up to 28dBi per antenna.
• Single/Dual Polarization Parabolic Dish Antennas – up to 37.7dBi per polarization or
antenna.
In FCC regions when using external antennas – cable loss between the Connectorized
version of the PTP 400 Series bridge and the antenna ports must not be less than 1.2dB
13.3 Software/Features
The variant operates in the same way as the basic PTP 400 Series Bridge product and is
released initially with the feature set of the Connectorized version of the PTP 400 Series
bridge. The areas where the functionality is modified are:
