Radar systems in WWII were BIG. This might possibly be one of the smaller land-based systems. Often multiple were used in a single installation. Although the base turns, it wasn't operated in a spinning mode like more modern radar systems. Since this is a terrain piece, I've gone for a relatively simple rendition of what was a very complex system of antennae in front of the mesh reflective surface. The mesh for the array's reflector surface is fiberglass window screen. The weave shows up prominently in these photos, but much less so in person and is 'close enough' to giving the right feel for me.
Below are some additional photos, plus one 'scene' with a bunker I previously built, a radio antenna my Uncle scratch built for me and an SdKfz 250 command half track and a couple of infantry figures for scale.
The diagram I built my model from, and a couple of historical photos from the web below.
I'm counting this as one (1) terrain item in my annual painting totals. This may be one of my favorite laser-cut original creations.
