The only real way to measure a balun is to put two back to back, then you
know you have the correct match and both ends are 50ohms to measure with. 
Total Losses/2, natrurally.

Does anyone know how best to test a balun, consisting of a quater wave 
section at about 1 GHz. Its quite a common design, with a tube connected 
to the braid of a coax quarter wave from the end.

I'm not sure how best to test this - near field probe around the coax ??
