[TowerTalk] RCS-8 as a StackMatch---How?

The information is in NCJ (National Contest Journal), 
November 2004, page 8.  "Improved Stack Switching with 
Invisible Stubs" by N4TZ.  

Remember, the N4TZ system is for monoband antennas and does 
does not work with multi-band antennas.  Stacks of Tribanders 
- particularly three antenna stacks - need a stack controller 
that properly matches the paralleled impedance over the entire 
operating range for any combination of antennas - not some 
compromise that requires retuning the amplifier (particularly 
high gain triodes with sensitive grids) as the configuration 
changes.
