[TowerTalk] Quarter wave baluns

[Steve Hunt]

Dan,

Some time ago I challenged G0KSC on a balun issue - you can read the 
discussion here:
http://www.g0ksc.co.uk/forum/2-antenna-discussions-here/122-pawsey-stub-error.html

You might want to read that discussion and then form your own opinion 
about his understanding of how baluns work!!
