of either grid or solid type are allowed. Maximum gain of each type of antenna
allowed 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: 26 dBi (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)
A complete list of allowed antennas can be found in Industry Canada (IC), Canada on
page 6.
EX-2.4i IC (Canada) EIRP
For the EX-2.4i models, maximum transmit power (Pmax) with respect to Industry
Canada EIRP regulations is unlimited. The output power shall never exceed +30dBm.
EX-4.9i IC (Canada) 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.
For the EX-4.9i models, the transmit power must be reduced from maximum (+24dBm
for 20MHz BW, +22dBm for 10MHz) by 1 dB for every 1dB that the antenna gain
exceeds 26dBi (including transmission system losses).
The professional installer is responsible to ensure that RF output power is properly
adjusted so that it does not exceed the regulatory limit of these conditions.
EX-5i IC (Canada) EIRP
For the EX-5i models, within the 5725–5850 MHz band, the maximum EIRP allowed is
61.9dBm. The maximum output power of the radio shall never exceed +24dBm.
For the EX-5i models, within the 5250–5350 MHz band, the maximum transmit power
with respect to IC (Canada) EIRP regulations is determined using the following equation:
P = 30 – G + L
where:
P = Maximum transmitter output power of radio, in dBm
G = Specified gain of antenna, in dBi, from 5250 to 5350 MHz
