Had to disassemble it for move in 2018. Sitting on the rear window ledge of my car, the sun bleached out all my magic marker markings. Now, to reassemble it, I need specs for each element's position. Fortunately I left the driven elements intact. I bought it used w/o any paperwork or mfg marking. To me, it's obviously a commercial product. All my searches have so far uncovered only 3 element 2m with 5 element 70cm commercial or homebrew beams. No sign of a 5 x 5. I shall attach some pictures of both driven elements and one each of the 2m and 70cm elements in hopes of one of them sparking a memory. The coax in the picture is the harness still connected to the drivers; they join at a T connector, to a single feed-line to the rig.
