If you operate in colder regions or your ship is docked in a winter harbor, you may have noticed: Snow and ice on your antenna are not exactly helpful when you need a stable connection. Flat-panel antennas, like the ones we sell, require an unobstructed view of the satellite to function optimally. But how do you remove snow from the antenna without damaging it? And what about other types of antennas, like Starlink?

Why Is Snow on Antennas a Problem?

Satellite communication relies on a clear line of sight between the antenna and the satellite. Snow, ice, or even moisture on the antenna surface can weaken or completely disrupt the signal. Flat-panel antennas are particularly affected since their flat surface allows snow to accumulate, significantly impacting signal quality. Unlike traditional parabolic antennas, they lack a curve that might allow some of the snow to slide off.

What About Starlink Antennas?

Starlink antennas are slightly tilted to prevent snow from accumulating. Additionally, many of the newer models come equipped with a heating function that melts snow as soon as a certain amount is detected. However, in cases of heavy snowfall, even this heating function can reach its limits. In such situations, gently sweeping off the snow or carefully warming the antenna can be beneficial.

The Role of Climate Control in Radomes

For large satellite antennas enclosed in radomes, where moving parts are involved, it is crucial to have proper climate control. Without adequate temperature regulation, moisture can freeze inside the radome, potentially causing the moving components to jam. This can lead to mechanical failure and signal disruptions. Ensuring a stable internal climate helps prevent ice buildup and keeps the antenna operating smoothly, even in extreme winter conditions.
