Fake CCTV camera. Affix to your marquee or tent! might deter someone from steeling your property. Or use it around the house / garage / workshop. Use a short length of threaded rod, screwed into the bottom off the antenna and then screwed into the main body. It might be necessary to run a tap / die-nut on the threads. I put a small blob of white nail-polish to simulate the camera lens. I printed in ABS

Added a wall bracket.
