[CQ-Contest] Coax Stubs for SO2R

Put a 23' Shorted stub on the 40 feedline (passes 40 and 15, 
rejects 20 and 10)

Put a 23' open stub on the tribander (passes 20 and 10, rejects 
40 and 15). Of course, you won't be able to use 15 with that stub 
on there.

23' is an approximation for RG-213.  Use instrumentation for 
exact measurement.  I use a dip oscillator.

             What would you recommend if you had  2 el 40 on one 
and  tribander
             on second tower.  I have considered experimenting 
so2r  but just 20 and 40
              meters to see if I can handle it.
