A dual trace oscilloscope is a good instrument to check the phase (and 
balance) of KLM baluns. 
The balun on the installed antenna should be temporary removed and 
checked. 
In any case the coax to the antennas will have to be the same lenght 
therefore also the already installed antenna and balun have to be 
accessed anyway.
