[Elecraft] OT: Coax Switch After the Tuner?

[Eric Fitzgerald]

Hello Wise and Powerful Reflector;

I have a couple of doublets I feed with balanced line.  The balanced  
line goes to a current balun and then a short coax run (5') to my  
tuner.  After the tuner I have another short coax run (3') to a coax  
switch that places either my antenna analyzer or the rig in the system  
so I can tune the antenna.  I've had it suggested to me that the coax  
switch places my precious K3 in danger.  The fact that this  
arrangement has worked up until this point isn't reassuring.  What say  
you all?

TIA,
