Hi folks, I’m trying to build that portable 4-element quad for 2-Meters from the ARRL Antenna book (1994 edition p18-30). The one thing I’m having trouble finding is the plexiglass used for the connection point. The plans call for a 3 ½ x 2 ½ inch sheet, so I don’t need a whole windowpane of the stuff. Anybody out there know of a source? Terry – KGØDU TNX & 73s
