[TowerTalk] 6M coax balun

[Jim Brown]

The problems with "string of bead" chokes are 1) that they are not 
resistive at the operating frequency, which makes them quite sensitive to 
the length of the feedline; and 2) they don't have enough choking 
impedance to do provide much noise rejection. Simple coils of coax with 
no ferrite cores have the same limitations. 

Again, study my tutorial to understand why.
