The accuracy of a Bird for measuring power goes out the window for an
SWR
other than 1:1. Are you saying that if you put an unterminated 3 inch
piece
of coax on the Bird you have a 50 ohm system? That sounds like
semantics
rather than Math. In fact you would have a 50 ohm system if you left
the
antenna port disconnected, Then you could say you had an unterminated
50
ohm system. Real handy huh?


Geesh! In the class, "Transmission Line 101", most basic fact is a
transmission line only is valid at its' stated impedance if terminated
in its' proper load/impedance ...

I think he took it for granted his text was formatted for the proper
audience ... he was simply mistaken, in your particular case. :-(

Now if you take 1000' of RG-174 and left it dangling over the end of a
cliff, the reflections wouldn't be able to climb back up the coax!
