The March 2013 issue of QST has another Antenna Tuner test by Joel, W1ZR.

This article is a good read because it also describes the ARRL's newest test
method for antenna tuners.

ONE OF THE BIGGEST MISTAKES I find people make in their thinking is, they
believe that if their ATU can match the antenna, that's goodness.  NOT!
In addition to whatever losses the antenna itself may have, there may also
be SIGNIFICANT matchbox losses. as this article points out on one of the
boxes.

The two Matchboxes tested here are the MFJ-976 and Palstar BT-1500A.
 <> What are their matching ranges?
 <> MORE IMPORTANT, how much power is lost in the matchbox when matching the
various impedances?

BTW, I have added these results to my "MATCHBOX SHOOT-OUT Spreadsheet" on my
web site.
It compares these tuners to others which the ARRL has previously tested.

A HUGE THANK YOU TO JOEL and his colleagues for reporting on this
interesting topic.
