> highly RF reflective What do you mean, exactly? Most of what you can find in the forest is 'RF reflective' because of the water contents - the trees, the grass, the ground. What's the proposed detection method that is going to discern a reflection from a small PCB from a reflection from a large tree trunk? edit: first, the camera isn't a retroreflector so you can't just light it up from any direction and get a strong reflection. Second, the kind of equipment that would give you good directionality with a static target is some next generation beam steering radar, that stuff is so expensive you're better off walking around with a 4K camera and then processing the footage with an image detector to find possible matches with images of trail cameras.
