[TowerTalk] Coaxial Stubs target frequencies for CQWW SSB

Here is the link to Jim Brown's great article on coax stubs.

http://www.k9yc.com/Coax-Stubs.pdf

The diagram I refer to is on page 12.

What I am hoping for is advice on a strategy for where to target the nulls
for each of the 10 stubs. 1850 for the 160m open stub could be good? 3600
for 80m shorted stub could be good since the null would be at 7200 on 40m?
There seems to be a strategy like that for each one.

Wondering what others have found good success with?
