No reception fransat in rainy weather

a choice of poor quality cable, poor sealing at the connection, poor alignment of the satellite dish (most likely cause), resulting in a signal that is too weak and during rain a highly interfered signal.

For receiving Fransat on the Atlantic Bird 3 satellite, the dish must have a diameter of 60 cm (resulting in a gain of 36.5 dBi @12.5 GHz) according to Fransat and Eutelsat. This size is valid for the central part of the beam in Western Europe. That's to start with.

Next, it must be perfectly pointed, with an error of less than 0.5°. If it is misaligned or displaced due to a gust of wind, it no longer provides the same output, with insufficient signal quality and intensity combined with rain causing additional temporary degradation, leading to pixelation or a black screen, starting with some channels and then affecting all 19 TNT channels and other regional ones.

An incorrect tilt of the universal head (polarization or cross-polarization angle) destroys the digital signal, as does water infiltration into the head through a more waterproof cap.

All these points need to be checked, including the connections.

Hi.
I saw LNBs with a small "umbrella" cover (or even a simple plastic bag) for protection against the rain.

If that can help you.

There may be one or more trees near the parabola in the direction of the satellite.

Hello, maybe the dish doesn’t have enough slope and the water stays on the dish; the remedy would be to place the dish on a higher point to lower its angle, allowing for faster runoff.
