Connecting Antenna(s) to the AP-4900M for 4.9 GHz Operation
To attach an external antenna to the AP-4900M, attach the selected antenna to the pigtail attachment connected to the
AP’s antenna connector 3 (see Figure 2-6).
For a list of recommended antennas, see http://www.proxim.com/products/wifi/accessories.

Adjusting Tx Output Power
Use the following formula in combination with the table of EIRP limits in US and EU countries to calculate system transmit
power (based on EIRP limits) of these countries:
Tx Power (dBm) = EIRP Limit (dBm) + FL (dB) – G (dB)
where:
Tx Power = Output power measured at the antenna input
EIRP Limit = EIRP limits specified below
FL = Feeder loss including loss of connectors
G = Antenna Gain
