• Use only parabolic dish antennas or directional flat-panel antennas. No other types of
antennas (omni-directional, yagi, and so on) are authorized. Parabolic dishes of either
grid or solid type are allowed. Maximum mid-band gain of each type of antenna
certified is:
¶ EX-2.4i models:
– Parabolic dish: 30.3 dBi (6'/1.8m diameter)
– Directional flat panel: 20.5 dBi (~2'/61cm square)
¶ EX-4.9i models:
– Parabolic dish: 26dBi (larger gains are allowed, with Tx power reduction)
– Directional flat panel: 26 dBi (larger gains are allowed, with Tx power
reduction)
¶ EX-5i models:
– Parabolic dish: 37.9 dBi (6'/1.8m diameter)
– Directional flat panel: 28 dBi (~2'/61cm square)
EX-2.4i FCC (USA) EIRP
For the EX-2.4i models, maximum transmit power with respect to FCC (USA) EIRP
regulations is determined using the following equation:
P = 30 - [(G - 6)/3] + L
where:
P = Maximum transmitter output power of radio, in dBm
G = Specified gain of antenna, in dBi, from 2400 to 2483.5 MHz
L = Total transmission system losses of all elements between the
radio’s RF connector and the antenna’s RF connector (all
cables, connectors, and lightning suppressors), in dB, as
specified or measured between 2400 and 2483.5MHz
The maximum EIRP allowed for the EX-2.4i models is 52.2dBm. The maximum output
power of the radio shall never exceed +30dBm.
The professional installer is responsible to ensure that RF output power is properly
adjusted to not exceed the regulatory limit of these conditions.
EX-4.9i FCC (USA) EIRP
For the EX-4.9i model, within the 4940–4990 MHz band, the maximum EIRP allowed is
+50dBm. The maximum output power of the radio shall never exceed +24dBm.
