John writes – “I saw this at my local Walmart today and HAD to get one. At first I thought it couldn’t be a real radar gun but the package says “10.525 GHz”. I took it apart enough to find what looks like a waveguide antenna. The screws are all covered with plastic plugs so taking it apart takes some doing.”Link.

Looks like something to check out for cheap parts / testing / radar projects.
