REMINDER:  Values show the "relative efficiency" with respect to the matchbox with the highest efficiency in this group test.

Very High =  Z > 400

Medium =  30 ≤  Z ≤  100

Again, we have no data indicating what amount of unbalance begins to cause trouble.  Most likely 5 or 6% will not cause problems; 10% possibly will.

NOTE:  ALL of the "Balanced Matchboxes" have worse balance than the "Unbalanced Matchboxes" using  an external balun!
