I put these guys back to work today after taking up space under my bed, while doing some work on my outdoor antenna to entertain my other hobby (Radio and TV DXing).The one on the top is holding the signal cable coming down from the antenna, and the bottom one is isolating the ground wire away from the fence. Some time this winter, when my pool can be moved out of the way, I'm going to lay the antenna mast down on the ground to clean the contacts at the top, and install another insulator up there to completely hold the signal cable off of the mast.
