Satellite dish
Satellite dish installation in Castellane
Dish fitting, precise alignment and satellite receiver setup: reliable reception, even where terrestrial TV is poor.
Satellite reception
When terrestrial TV won't come through, we aim at the sky
A terrestrial TV aerial has to pick up a ground-based transmitter, sometimes hidden behind a ridge. A dish, on the other hand, points at a satellite: in a deep valley, that is often what works best.
TV satellites sit above the equator. From France, the dish therefore needs a clear view to the south: this is the first thing checked before fitting.
Alignment
Three adjustments to get it right
Even a slight error in alignment is enough to degrade reception. Alignment is adjusted on three axes.
- Azimuth: the direction, to the left or to the right
- Elevation: the pointing angle above the horizon
- Polarisation: the rotation of the LNB (receiving head)

Equipment
Dish, LNB, satellite receiver
The dish focuses the signal onto the LNB, which is connected to the satellite receiver by coaxial cable. Every component matters: a worn LNB or a damaged connector is enough to cut the reception.
Terrestrial TV (TNT) channels are also broadcast by satellite, with no subscription, using a compatible receiver and card. Other channels depend on the satellite targeted (Astra, Hotbird) and on the access terms of each channel package.
An existing dish that no longer receives anything is a matter for repair. For satellite internet access, see Starlink installation.

Frequently asked questions
Your questions
Do I need a subscription to receive channels by satellite?
Terrestrial TV (TNT) channels are available by satellite with no subscription, using a compatible receiver and card. Other channels or packages may require a subscription with their provider.
Does the dish have to be on the roof?
No: it can be fitted on a wall, a balcony or a mast on the ground, as long as the view to the south is clear.
Do rain or snow cut the reception?
A very heavy storm can weaken the signal for a few minutes. If the signal drops out frequently, the dish is probably misaligned or the LNB needs checking.
