I noticed that my CG-1500 enclosure has some "knobs" on the back of the enclosure. Does anyone know--are these intended to be incorporated into a unistrut mounting bracket or a mounting bracket similar to unistrut? I haven't gotten this far yet, but in the next few weekends I will have to figure out how to mount my CG-1500 in the yard. I don't want to put on the ground if at all possible. I actually have a "transformer box" (19kv yikes) in my front yard that I am thinking about "hiding" my CG-1500 behind; would be a good spot for it pretty close to my arches. Thanks very much in advance!!
