What should be checked when inspecting satellite dishes?

When inspecting satellite dishes, it is essential to verify that the weather caps are in place and in good condition. Weather caps are designed to protect the inner components of the satellite dish from moisture, dust, and other environmental factors that can compromise performance. If these caps are damaged or missing, it could lead to water ingress, corrosion, or damage to sensitive electronics, ultimately resulting in poor signal reception or complete system failure. Ensuring that they are intact helps maintain the dish's integrity and performance in varying weather conditions.

While considering other aspects of satellite dish functionality, such as the availability of cables or the surrounding area being clear of obstructions, these factors do not specifically address the protection and maintenance of the dish's internal components like the weather caps do. The color of the dish, while potentially relevant for aesthetic purposes or uniformity with a building's exterior, does not impact the functionality of the dish. Therefore, focusing on the condition of weather caps is critical for optimal satellite dish operation.
