FWIW here is an online calculator that calculates ERP and EIRP values http://www.csgnetwork.com/antennaecalc.html
you can see what different combos of antennas and amps do. I've found it handy to make sure a meraki with a 500 mW amplifier and a 9 dBi antenna is just under the legal 4 watts EIRP used in the golden hill network > The FCC rules are actually a bit more complicated than that.
