The hairpin match , yes a very good question indeed.
In fact, so good that Hygain didn’t choose to answer it in
their instruction manual. They show all the parts for it, including
what looks like an adjustable shorting bar, but absolutely no
mention of it in the text. DX Engineering is still selling them, with
the exact same manual. What a joke.
