Under really bad conditions - not just rainand snow but tropospheric - a signal can fade as much as 26dB, at least when we did 450MHz links that was always the planning margin.
I would look for at least a 12dB or preferably an 18db attenuator to make sure.

I think we would need much more details about your location to answer this question. What do the neighbours do? You can often get a good idea from that. Brian
MY next door neighbour's dish is mounted high soi that it can see over my house. When I had a dish (analogue days) it ws only 6 ft above ground - but the hedge has grown and it would need to be higher now.
I'm also around 20 miles from a transmitter (Bluebell Hill) and a short periodic in the loft followed by a lowish gain amp worked perfectly for me for over a year. I decided to install it on my chimney when I had the roof replaced and the scaffolding made access to the roof easy.
A log periodic of around a metre in length is ideal for fitting in a loft where space for it a larger array may be a problem.
No, satellite IF distribution is easier than terrestrial.

Or a lowered hedge...
Sometimes the height is necessary because of an obstruction that can't be seen from the street.

but, it's not mine.
If you still want Freeview rather than Freesat, I suggest that you seek advice as to what aerial to get.

If you have enough DDTV signal to split. A passive 4 way split will cost you at least 6 dB. 8 way split would almost certainly need an amp so is pretty much the same as a multiswitch.
The other advantage of Freesat is the higher bit rates and thus better quality. Freeview is barely watchable. More channels to flip through and decide they are all crap. B-_
If buying a satellite box/pvr these days would you not purchase one that supports unicable LNBs?
Many of the Enigma 2 box manufactures seem to be going down this route with their new offerings.
And a low chimney mounting can be far more subtle than a dish on the front elevation of the property.
That is something that often annoys me. Unless the house roof is particularly tall in most cases a dish on a pole about 1m above the gutter will see over the roof from the back. Saves all of those monstrous carbuncles on the front! IMO they are fitted on the front for the convenience of the installer and using less cable in most cases.
Mine is on the front of the house because it is the only place it could go and "see" the satellite through the gap between the chimneys of a house across the road and the tree in its neighbour's garden. If I mounted it at the back of the house, I would have to screw the pole to my neighbour's house in order to see through that same gap. That would not have been neighbourly.
Sometimes, practicalities have to take priority over aesthetics.

I mounted my dish at ground level, facing my terraced house, at the far end of my back garden under a tree. Satellites are well above the roof level from there. I painted the dish black for minimum visibility.
