Hi again RVAUGHN! Radar on Lake Lanier? Unless you're setting the boat up to go back to the coast someday, not sure why you'd install radar for the lake, it's just not needed. While the mast is down consider rewiring, replacing light bulbs, antennas, adding spreader lights, and a good rigging inspection, especially if the boat is coming from salt water. Send me a PM if you have questions about marinas or the lake itself if you are not from the area.
