• Do not use external amplifiers to boost the power or overcome transmission system losses,
unless the specific amplifier/cable/antenna combination has expressly been authorized by the
FCC. The output power must never exceed +30dBm.
• Cross-border transmissions are expressly prohibited, except with written permission from
both the FCC and the governing body of the neighboring country (Cofetel for Mexico;
Industry Canada for Canada).
• 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-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-4.9r FCC (USA) EIRP
For the EX-4.9r 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-4.9r models, the transmit power must be reduced from maximum (+20dBm for 40
MHz BW, +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.
FCC (USA) EIRP
Within the 5725–5850 MHz band, the maximum EIRP allowed is 61.5dBm. The maximum
output power of the radio shall never exceed +24dBm.
Within the 5250–5350 MHz band, the maximum transmit power with respect to FCC (USA)
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
