EIRP Limits for the United States and Canada
EIRP for the USA and Canada
4940–4990 MHz Band
For the ExtendAir (TDD) Series 4.9xx models, within the 4940–4990 MHz band, the maximum EIRP
allowed is +50dBm. The maximum output power of the radio shall never exceed +24dBm.
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)
5250–5350 MHz and 5470–5725 MHz Bands
For 5250–5350 MHz and 5470–5725 MHz bands, the maximum EIRP is based on the bandwidth
selection of the radio. The maximum output of the radio is +22 dBm.

EIRP – G + L
where:
5725–5850 MHz Band
For all models within the 5725–5850 MHz band, the maximum output power of the radio is +22 dBm.
The radio may operate at full power into the maximum gain antenna specified, which is 37.9dBi.
Note: The professional installer is responsible to ensure that RF output power is properly
adjusted to not exceed the regulatory limit.
P = Maximum transmitter output power of radio, in dBm.
EIRP = 26.38 (for 8MHz BW selection), 29.41 (for 16MHz BW selection), or 30 (for 32MHz
BW selection)
G = Specified gain of antenna, in dBi, at the operating frequency.
L = Total transmission system losses of all elements between the radio’s RF connector and
the antenna’s RF connector (all cables, connectors, lightning suppressors), in dB, as
specified or measured between at the operating frequency.
