RF Power combiner? I've used RF splitters fairly often, so while I have no direct experience going the opposite direction, I think there are plenty of companies that will sell what you need. One reference covering some basic questions: http://www.minicircuits.com/pages/pdfs/pwr2-4.pdf Good luck, Doug -- Doug Geiger doug.gei...@bioradiation.net _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
