http://www.tuc.nrao.edu/%7Edemerson/helixgain/helix.htm WebIn addition, there are peak antenna gain rules that are specified in dBm. Typically, antenna gain is specified in dB, such as peak antenna gain equals +2 dB. This means that the efficiency times the directivity is +2 dB. FCC rules often specify gain in dBm. This means that they might say the wifi antenna gain must be less than 10 dBm.
