You can then optimise the incoming wall of RF. -------------------------- Actually it is probably better to put the antenna across the 100-ohms and connect the Datong to the slider. This is more likely to maintain the Q of the antenna, and hence its selectivity. Mike, G3XDV http://www.lf.thersgb.net =================
