It's one of the greatest gadgets for setting an antenna tuner you'll 
find.  Hooked in the line with a switch to select either the input to 
the tuner, or 259 you can adjust the tuner of 52 ohms X=0, tune the amp 
into a 50 ohm dummy load, switch amp to the tuner and you are set to go 
without ever putting a signal on the air.
