16.3.8 PTP 58300 FCC Antenna Restrictions
In FCC regions, external antennas from the list in Table 53 can be used with the
Connectorized version of the PTP 58300. These are approved by the FCC for use with the
product and are constrained by the following limit for Single/Dual Polarization Parabolic Dish
Antennas: up to 37.7 dBi per polarization or antenna.
In FCC regions when using external antennas, cable loss between the connectorized version
of the PTP 300 Series Bridge and the antenna ports must not be less than 1.2 dB.
NOTE
When operating PTP 58300 with a 5 MHz channel bandwidth and with dish antennas
larger than 4 ft (1.2 metres) diameter, the maximum operating power must be
reduced to 24 dBm (3 dB reduction) to ensure that FCC requirements are met
CAUTION
Antennas not included in this table, or those having a gain greater than the specified
maximum, are strictly prohibited for use with the PTP 58300. The required antenna
impedance is 50 ohms.
