Here's an image of the antenna mount. It is screwed in to a hardpoint of 1/4 inch plywood on one of the frames and is cut from 1/8 inch ply. In keeping with Futaba's instructions, the antennas are orientated 90 degrees apart. I still like the idea of keeping at least one of them vertical over the surface of the water. It should help with the reception during my trips to the other side of the lake. Dan.
