..hhmm - I think - actually I know - that I'm confused about this topic regarding LNB, DiSEqC - and now also switches..
I had a professional company set up everything on the roof and down to the receivers..
Slowly I'm starting to dig into this satellite system - and I find it quite interesting - even to the degree that I want to completely take it over myself - eventually ending up with a Satlook Digital NIT to adjust the dishes and LNBs myself in the future..
I have 4 LNBs - with 4 cables each - and one cable from each LNB goes into 1 DiSEqC..
Then - from each DiSEqC - goes 1 cable down to 4 different receivers..
I can do all receiver setup fine now..
But my interest has started to move also towards the setup on the roof - and what I'm a bit unsure about is:
What does the DiSEqCs actually do..? Are they the switches - same as the LNB with switches..? And if so - cold I then scrab the DiSEqCs and have everything in the LNBs - or am I mixing things up..?
And would a LNB with switch (opposed to the ones I have now without switches) do me any good - or would they be waste..? I use only 4 or 5 receivers in the whole house..
Also - where does the power come from - is that brought down through the dish and LNBs together with the satellite signal..?
Or is the power coming backwards up through the coaxial cable from the receiver power..?
Ha - ha - that's probably one Q which will have you guys roll over on the floor with laughter
Finally - my LNBs are 0.6db - would new ones with 0.2 or even lower be a big difference in TV picture quality..?
