here is a good easy project. these actually do work, and yes they are ugly.
i used a 4 inch diameter black drainage pipe. the type with holes in it, this way i dont have to make holes in it to tie the coax. take about 18-21 feet of coax and coil around it. do not cross over the coax just coil it beside itself. use zip ties to hold it in place. the number of coils are not important, the length is more important. these help keep stray rf from entering your shack. i put mine close to the feedpoint as possible. try one for yourself you will be suprised.
