This was important in the old days when rigs put out harmonics. I got
a "pink slip" as a novice years ago for being on the 40 meter band when
I was suppose to be on 80 meters.

[Repeater-Builder] Antenna tuner question - slightly OT

Gents

I need a quick reply to this very pressing question. I have an HF 
antenna tuner that uses 2 roller inductors and 1 large air variable 
cap, versus the more popular arrangement of 2 varicaps and 1 inductor.

What is the 2 inductor - 1 capacitor arrangement called?  Certainly 
not a T-Match (I don't think)

Thanks
