Rain Satellite Interference Guide

Your satellite TV signal cuts out every time it rains hard. Here is exactly why that happens, when it is a dish problem you can fix, and when it is unavoidable physics — plus the practical steps that actually reduce rain fade.

How Satellite Television Reception Works

UK satellite television signals are broadcast from geostationary satellites at approximately 35,786 km above the equator. Sky and Freesat services transmit from Astra 28.2° East. The dish must be aligned precisely — a misalignment of even two or three degrees substantially reduces signal margin and causes picture breakdown during adverse weather. The LNB mounted on the dish arm converts the satellite signal into a lower frequency for the coaxial cable. Incorrect LNB type or a degraded LNB is one of the most frequently misdiagnosed causes of satellite signal problems.

Common Satellite Signal Problems

• No signal at all: Usually a misaligned dish, failed LNB, or damaged cable
• Pixelating or freezing picture: Signal is marginal — dish alignment, water in connectors, or undersized dish
• Signal dropout in bad weather only: If it occurs in light rain, alignment is insufficient and needs professional realignment
• Some channels missing: Weak signal on specific transponders — alignment or LNB upgrade typically resolves this

Professional Satellite Installation and Repair

Everest Aerials engineers align all satellite dishes using professional signal analysers — measuring actual signal strength rather than relying on the signal bar on a receiver. We align for maximum signal margin so reception remains stable in poor weather. LNBs for Sky Q, Freesat 4K, and multi-room configurations are carried on every van.
