A few answers
I have some questions concerning about FTA:
1. Which one should I start? Ku-band or C-band?
Ku is probably easier. Smaller antenna to deal with.
You'll learn all the fundamentals, so C band won't be too big a challenge later.
2. Will I need to have two dishes: one for Ku-band and one for C-band?
What about one dish for Atlantic sats and another for North American sats?
A 90cm (36") to 1.2m (4') dish to start on Ku will often perform as well as many 8-10' BUDs.
It would simplify things to add an 8-10' BUD for C band only, at a later time.
Some more advanced members might describe both bands on their BUDs, that'd be paddling upstream for a beginner.
3. I'm considering getting a motorized offset 1.2 meter dish for C-band, since they're easier to install than the prime focus dishes with 1.8 meter and above. With a quality 1.2 meter dish like the one from GEOSATpro, a quality C-band LNBF like the one from DMS International and a quality satellite receiver like microHD, would I get more channels and feeds on each satellite? I knew that most Atlantic and North American satellites have an EIRP beam of 38 dBW and above here in Burlington.
Regardless of power output, your dish needs to be able to reject the signal from 2 degrees to either side if the desired satellite.
That's why 12-16 foots are used commercially on C band.
We can often skate by on 8-10' BUDs.
Dont waste your time & money on 4' nor 6' dishes on C band.
For Ku, the SatAV 1.2m dish would be excellent!
Atlantic satellites on Ku just need a Universal LNBF to receive 'em.
So your one dish is fine.
Atlantic sats on C band might need a circular LNBF.
There ways of mounting two LNBFs, and other solutions.
Way beyond the scope of an introductory post.
4. If I have a big, fixed C-band dish and I switch from one satellite to another by moving it manually, is this possible when the satellite receiver is on?
Yes...
Though, we'd normally just have the receiver command the motor controller (Vbox or Gbox) to move the dish.
5. Is possible to have FTA in two rooms, especially my room and the living room?
Sure. Two output LNBFs and proper wiring will get it done.
See the Switches Simplified thread in our FAQ department.
However, I wouldn't complicate my life with that 'till I'd mastered the basics.
6. What are the differences between LNB, LNBF and "Turbo" LNB?
lnb = low noise block converter
converts a block/range of microwave frequencies (10-12ghz for Ku, around 4ghz for C band) to a lower range (1-2ghz) to be handled by the receiver
lnbf = low noise block converter with feedhorn (see SatAV site for an assortment of Ku LNBFs)
turbo = meaningless marketing hype & B/S, as are claims of 0.1 db N/F
