well here in rochester the winters are ruff to say the least So I have mounted as much of my contollers and power supplies inside. This is my basement. There is the DMX controller for the gift boxes and floods. The F16v2 will directly run the Mega tree and lights around the door and windows. My differential board will run 4 receiver boards in the attic and garage with only 2 outside in the elements. Seperate fuse boxes have been added for power injection. The FM transmitter will wired for the antenna to be outside.
