Welcome,
Sounds like there was a 'loftbox' system set up previously.
You require:
1 > Quad LNb and separate sat/uhf/fm diplexers for each of the 4 points but this would not help you if you wanted Sl<y Plus / Sl<y Hd in the future as you would require more satellite IF feeds although this would work fine with four points only.
OR
2 > Systems LNb (quattro) into a 8 way Satellite Multi-switch. UHF, FM and four fixed feeds from the dish into the switch and then connect up your four feeds to the outlets. Change the outlet plates to Triplex Plates (Sat, TV/FM).
This would be a future proof system as you would have four free feeds from the switch which could be connected up later.
