does anyone have an experience with the s-match atu? http://www.i1wqrlinkradio.com/antype/ch7/chiave1584.htm i have long given up coax (literally, friends have taken it away). i have one piece that i use with my 20 meter yagi. but the z-match on my micro-doublet (51 feet wide) is less than optimal. i was thinking of the s-match. any pointers to how this can be tested on the bench? i can throw this together in an hour. what next? all my instrumentation is for unbalanced 50 ohms working. - f

Hello Farhan, I have never used one, but it is quite popular in the Netherlands. There is even a commercial version available (PA0LL). Have you visited PA0FRI's website? You can find it here: http://www.pa0fri.com/ There is a lot of information on ATU's. 73, Roelof Bakker, pa0rdt
