On fixed dishes, this is a good time to mark the dish with the permanent marker. When you know you have the dish properly peaked, draw a vertical line down the mount shaft. Because the line on the pole will align with the line on the mount shaft, if the dish shifts because of wind or vandalism, your technicians will be able to move it back into proper alignment quickly. With your wrench, firmly tighten mounting bolts, inspecting for loose or missing hardware. Make sure that all the panels are properly aligned.
Winter winds can deform dishes when mounting hardware is loose or missing.
On Cassegrain dishes, inspect the back of the dish and the feedhorn tube for nesting animals. Squirrels especially like the security these structures provide, and they just happen to have a natural tendency to chew on cables, which can make your life a nightmare. Do what you can to seal these areas. The multiple cable runs inside the feedhorn tube made an excellent support structure for a squirrel's nest. Keep an eye on pressures While the weather still is tolerable, it's also a good time to check cable and feedhorn pressurization equipment.
