Bob:
My diodes are schottky... My "key" has always been shot.... sorry, couldn't resist... no one make more typos then me... grin Warmest regards, John "Bob Bob" wrote in message ... | Yep I use that configuration for a directional coupler/VSWR measuring | device some years ago. I ran the internal insulated lines up either side | of the coax (RG213) into a switch box and off to a DVM. I think I used | shottkey diodes. | | Cheers Bob VK2YQA | | Cecil Moore wrote: | I vaguely remember building a coaxial "slotted" line without | the slot when I was in college.
