2 x 4 to 1 voltage balun in series
can someone explain how to connect 2 voltage 4:1 baluns in series to
achieve 16:1
=================================
With say one 4:1 balun having 2 windings Aa and Bb and the second 4:1
balun having 2 windings Cc and Dd with A & a etc the ends of a
particular winding , connect the windings as follows :
a to B , b to C , c to D
Connect grounded unbalanced side to bC connection
Connect the hot unbalanced side either to aB or cD connection
Connect balanced line between A and d
The above applies when the 2 existing baluns being wound with 2 windings
each with the 2 corresponding ends being A and B , a and b for one
balun and C and D , c and d for the other balun.
I should have made an ASCII drawing of the 4 windings in series ,but I
didn't expect it to be transmitted correctly ,so I hope the above
description makes sense .
