Tony, can you find out the details of this? I can't see why there
should be any 32 dB constant involved. I think it should be
simple as receive antenna gain minus cable loss plus transmit 
antenna gain.

This arrangement can even appear to have some gain -- which
is possible if the transmit antenna has narrower beamwidth
than the receive antenna.
