This is the smallest Desktop Transmatch I have seen. Fully built or a full kit with all the parts you need to produce a 3.5 to 30Mhz Transmatch. The MTM-ATU uses a resistive bridge SWR indicator and makes it easy to find a match by just watching the built in SWR indicator LED as you tune, simply adjust the two controls for the led to go out and you have a match. Simple to use and faster than many manual ATU's due to only having two controls with a fixed transmatch inductor built in.
