Attenuation with External Antennas

If external antennas are used, it is necessary to adjust the transmit power attenuation to provide
the correct power level for the router. Use the following formulas to compute the required
attenuation level:

Gain’ (dBi) = Antenna Gain (dBi) - Cable Loss (dB)

802.11b/g:

802.11a:

Tx Antenna Setting (dB) =

Gain’ - 7

if Gain’ < 7 dBi

if Gain’ > 7dBi

Tx Antenna Setting (dB) =

Gain’ - 5

if Gain’ < 9 dBi

if Gain’ > 9 dBi
