Its that time of the year when the sun causes some small satellite signals reception issues.

 

This happens around March and October time, around the time of the Spring and Autumn Equinoxes.

 

For the next week or so, the suns path across the sky take it directly behind the UK TV satellites.

 

During this time, the energy from the sun swamps out the  weaker signals.

 

This results in a loss of some channels, like BBC ITV C4 and Fives.

 

At the moment this is around 1030-1130, and lasts for approximately 10-20 minutes.

 

On the flip side, at around 2230-2330, the satellites are in the earths shadow, and so not operating on full solar energy, but moves to battery backups. These backups have less power, and can mean a small drop in signals, again affecting the weaker BBC ITV C4 channels.

This does not usually affect viewers in the UK, but will affect those in the “fringe reception” areas, like Spain Portugal and the south Mediterranean.

Reposting this as some people are unaware of this :

It is coming to the time of year, when the sun moves directly behind the satellites, and can mean that for a brief period of time (about 10 mins) you can lose some satellite Tv signals in the morning – between about 1030 and 11 30.

This is basically because the suns energy swamps the weaker signals (eg BBC itv) causing a brief period of channel loss.

The channels should return by themselves once the sun moves out of the way

Smaller dishes will be affected more than larger dishes.

On “big” prime focus satellite dishes you can tell when this is happening, as the shadow of the LNB is right in the centre of the dish – indicating the dish is pointing directly towards the sun and satellites. And it is a good time to see if there is any shrubbery that is covering the “line of sight” to the dish which can affect reception.
