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
tower
and tribander
on second tower. I have considered experimenting
with
so2r but just 20 and 40
meters to see if I can handle it.
