Topband: 160M Balun

[Jim Thomson]

##  Much higher  Z....and much higher  RS....and minimal Xs.
Plan B would be to use  RG-400... but more than 7 turns.

##  N3RR has his  160m  CM chokes between 16k and  22k  ohms.
If you are going to build a 160M  CM choke,  you may as well do it right
the 1st time.

Why do you want it resonant?

The  160m CM choke needs to resonate lower in freq.  It requires  more cores
to shift the res freq down.
