Hello Group,

I will install an Off Center Fed dipole for 160, 80 and 40m.

I need a 4:1 CURRENT BALUN (NOT VOLTAGE BALUN) to avoid that antenna current 
can flow on the feeder...

In the Antenna Book chapter 26 I can see a current balun but said "balanced to 
balanced", is it ok???...

in my case (OCF) both sides are unbalanced, the 50 ohms coax cable and the OCF 
dipole legs are unequal...

I dont know what to do...any idea???...I need schematic of building that kind 
of 4:1 current balun unbalalance to unbalalance.

thanks,

Doug, CO8DM
