[Moon-net] balun

[f6dro]

Hi all ,
for more information see:
http://www.freescale.com/files/rf_if/doc/app_note/AN1034.pdf  ( fig 3)

the DJ7ZB "balun" is similar to design 1 , it is perfectly clear than once 
you don't know the charateristics of the transmission line formed by the 
coaxial braid and external world , you have no garantee this is acting like 
an high impedance . Some compensation/tuning  is needed , or using another 
balun design.
