Daan - Here is the match I get for your problem: Input C 226.6 pF Coil 1.2 uH Output C 174.7 pF SWR 1.0 Percent loss 1.0 dB loss 0.0 (actually this means less than 0.1, teh lowest value the applet shows) It is a bit different than yours and the automatch, but it is low none the less. I get the

While a T-network is not necessarily lossy at moderate impedances, try using one to load up a short antenna. For example, a 25 foot end fed wire on 80 meters will show an impedance of about 3-j550 ohms. A T-network tuner will match it okay, but with a loss of 7 dB! That's a loss of about 79% of

I broke your tuner! snip W9CF wrote a fun little T-match simulator that gives you a front-panel view of a tuner. You plug in the impedance you want to match and press Autotune, and it'll find the match and give you the circuit loss. And you can spin the dials manually and enjoy watching the SWR
