Hello, I just ordered an unun and a balun from ebay. They are coming without a project box. They cost around $14 or $15 including shipping. When I looked at plastic boxes, they were all $12 or more with shipping. It bothers me to pay more for the box as the unun, as at that point, I could have just bought one all put together in a box, had I known. (I know, that is why the ones without the box are cheaper.) So, looking for something, I saw my wife had just thrown out an squarish Arm and Hammer disinfectant wipes box that has a little door that is waterproof, (as it has to prevent the wet wipes from drying out), and can be cut down and taped back together and will make a nice balun and unun box. Any other ideas?
