How Can I calculate EIRP?

Hi folks,

What is the maximum EIRP allowed on a point to point wireless link?

I am using Cisco Aironet Bridge 1410, and the Cisco 5.8 GHZ 28dBi dish antenna

I have set the Air bride to 24dbm/250mw, let me think loud

The EIRP = Tx Output Power (dBW/dBm) + Antenna Gain (dBi) - Line Loss (dB)

= 24 + 28 + 1.3 (for 20ft cable) = 53.3 db

Now if want to convert this amount in watts, then I will use this equation

53.3dB = 10 log (P in mille watts) 5.33db = 10 log P p = 213796 mw or 213 watts :( I am sure that I am wrong.

I know that for multi point the maximum EIRP is 4 Watts only

I will appreciate any help
