The maximum FCC permited transmit power is +15dBm, coupling to an impedance matched antenna caused 50% power loss which is -3db down. Most standard built-in antennas are 2dBi to 4dBi and brought the aparent radiated transmit power back to normalize maximum.Kevin16 said:Hi Guys
Does anyone know what the approx. gain on a typical cardbus wireless network adaptor (no external antenna) is?
I'm asking this because I am planning on buying a new antenna with a higher gain.
Thanks,
Kevin
