That's for sure :-)

This (1.92W) is almost identical to the result (2W) of the calculation below

which is using the same formula, but with the input power expressed in dBm
instead of W (since it's easier to just add the two figures)

Yeah, that is confusing (the little converter is handy though)


Ahhh, what the heck, just plug it in, point it in the right direction, and
see if it works :-)
