I recently made a 2m yagi tape measure antenna out of 1/2 inch schedule 40 PVC pipe to listen to some satellites pass overhead. I quickly realized that it would be easier to mount my radio on the antenna for ease of handling. This is an original design I made using Fusion 360. I needed a project to help me learn it ;)
I currently have a Baofeng UV-5R clipped to it, but it should work with most belt clip HT radios. I even made a coax clip which should help keep the cable tidy while using. It snaps tight and seems to stay in place really well on the pipe. Enjoy!
