[TenTec] T tuner (transmatch) losses?

[Stuart Rohre]

That is consistent with the tuner measurements article in QST some years
back.
Murch was a rugged component tuner.  Still good if you can find one.   Most
tuners are limited by goodness of the balun.  For lower loss, at Field Day,
we used external 4:1 baluns after the coax output jack of tuners and then
ran into 450 ohm or 300 ohm ladder line.

Also see Tuner loss tests in QRP-l archives reachable from "QRP-ARCI
webpage" found by google.com search.
