A 4x8 or 5x8 if diplexing an antenna into the switch would be most appropriate. The only ones I know of are powered to provide proper voltage to the LNBs regardless of length of run and to amplify the signal enough to overcome the 8 way split. Eagle Aspen 4x8s and 5x8s as well as the Terk BMS-58 are inexpensive and work well. The Terk can be mounted outside. The EA S-4180-GX+ needs protection from the elements. I recommend an indoor mounting to keep the connections dry. The switch needs 5 or 6 RG6 lines in including 1 for 24VDC power which originates indoors. It can output 8 lines so putting the switch indoors would normally result in less building penetration.
