Receive More Than One Satellite
- Perhaps the most obvious and probably
the best way of receiving satellite signals from more than one satellite or orbital position would be just to install extra satellite dishes.
- You could install one for the country that you are in, for instance in the UK this could be for Sky/ Freesat and a second for the other countries TV that you want to receive
- for example Italian Tivusat TV
from Hotbird at 13E
Doing it this way would be the least likely to fail as there are no moving parts and you can put up the exact size dish for the satellite in your location
- Using the above example again here in the south of the UK a 45cm satellite dish is fine for Sky & Freesat and a 70-80cm would be ideal for Hotbird reception.
The downside of doing
- it this way obviously if you wanted to then receive from a third satellite you would need to install a third satellite dish or make alterations to one of your existing satellite dishes.
- Plonking loads of satellite dishes on your property also may not make you popular with the wife/ your spouse or even be allowed under local planning rules.
- Believe it or not to install more than two satellite dishes on one property in the UK requires planning permission.
- I’m not saying that?
this is always adhered to or even enforced but you may find that you receive an order in the post to remove one.For you reference you’re allowed to install without planning permission in the UK two separate dishes, one up to 60cm and one up to 1m without planning permission
Multiblock LNB Holder
You may or may not be aware that it is actually possible to point one fixed satellite dish to two or more orbital locations by installing extra “offset” LNB’s on this one dish. To understand how this is possible a quick description of
how a satellite dish works helps
- A satellite dish is pointed to receive signals that are broadcast from satellites in space. The signal bounces off the big back reflector towards the LNB where it is transferred onto the coaxial cable.
- The big back reflector is usually round or elliptical part of the dish although some manufacturers have otherdesigns.
- As the signals bounce of the back part of the dish it is possible to install the satellite dish so that the signal bounces off at a different angle than the normal central LNB position to a LNB that has been installed offset to the right or left of the central LNB position.
LNB’s onto a single satellite dish is perfect for receiving satellites that are relatively close together.
- 10 degrees or less like for Astra 1 and Hotbird reception with are only six degrees apart.It is possible to install a fixed satellite dish with LNB’s that are further apart and many dishes offer 15 degrees separation between satellites but I wouldn’t recommend it. This is because the further
- you deviate off the central dish pointing location the weaker the received signal will be. This can be overcome with a larger satellite dish but you may need to go much larger than is necessary and installation can become difficult if you’re attempting to do this yourself.
- To do this I would recommen
purchasing a multiblock LNB holder. I use Triax satellite dishes and a two or up to four LNB holder for this task. A description of an installation to receive satellite signals from Astra 2 at 28.2E and Astra 1 at 19.2E for English & The central dish position would actually be in between the two satellites at around 23
- degrees with both
LNB’s offset so that neither is deviating too far off the natural pointing angle of the satellite dish. I would use a 80cm satellite dish for this task but you may need a 1m in the north of England and Scotland. The LNB’s will then be altered individually 7sat.org to maximise the signal from each satellite.
- It can take a bit of playing around but if you’re patient you could remove the need for a second satellite dish altogether.
- Extra LNB’s can then be added for extra satellites if they are also close to the natural dish pointing angle.
