Topband: To Balun or not to Balun that is the question.

I'll measure some Hygain Baluns and a few air coils when I get time.

The BN86 is a bead balun like the W2DU style balun but with different bead
material.

Hygain sent me some baluns when they were going to change to a 73 material,
but I nixed the change because at ~1000 watts the baluns reached curie
temperature and quit being baluns.

73, Tom W8JI
