The Xsarius Paratprot umbrella for your dish, gives around 6 dB gain in rain and fog, the difference between picture and no picture.
Snow showers can lead to interference with TV reception. Especially users of smaller satellite dish systems should take into account temporarily disrupted reception in heavy snowfall. The 'umbrella' protects the LNB and prevents the picture from disappearing while you are watching your favorite TV program.

Suitable for satellite dishes with one or two LNB.
