Actually, the terminology is a little slippery here.

On the transmission line there is energy being conveyed toward the antenna
via a FORWARD traveling wave.

Similarly, due to the reflection process, there is energy being conveyed
away from the antenna via a REFLECTED traveling wave.

The NET POWER being delivered to the antenna and being radiated, less
antenna heat losses, is simply the difference between the Forward and
Reflected power values.

The Bird is reading either the FORWARD power or the REFLECTED power.
Subtract those two readings to get the NET POWER delivered to the antenna
to be radiated.

Don't you just hate these nit pickers!   <:}
