Hi Steve: I'm not familiar with "CB" screens, but for outdoor use I made a cheap, simple screen that works great. I purchased some 95" movie screen material (fabric) off of ebay for about $20, then made a wood frame. I pulled the screen around the frame & used a staple gun to hold it in place. To finish it, I taped off the inside of a border and spray painted the 4" border flat black. I use two screw hooks on top of the screen to attach it to two eye hooks on my outside deck. The whole thing cost about $40.
