[QUOTE="closetosoton, post: 86333, member: 184281"] I have had another response for an RF type person: [I]"Should not matter one way or another: since the switch is basically a passive device its contribution to noise figure will be the same wherever it is placed. There might be some slight subtleties depending on the Return Loss presented to the cable by the different switch ports, but really not worth worrying about..... Incidentally, unless your cable is phenomenally long or your receiver even deafer than it should be, an increase in LNB to receiver loss of 3dB or even 6dB should not make a blind bit of difference to received error rate/picture quality, as LNBs are normally designed to provide enough excess gain to overcome the loss of said phenomenally long feeder."[/I] [/QUOTE]
