1) Can I use standard single LNB to connect more than one receiver.

If you want each receiver to have independant control of the channels, you will need to use a dual outpt LNBF. If you want to watch the same channel (or same polarity channels), you can use a single LNBF connected to one receivers. The 2nd receiver is connected to the 1st receiver using the "loop out"

(Loop out connection is below LNB In)

2)What is the difference between LNB standard and LNB universal

---------------------Standard----------- Universal
Freq Range:---- 11.2 - 12.2 GHz------10.7 - 12.75 Ghz
Lo Freq:--------- 10750 ------------ 9750,10600
22Khz tone:-------- Off---------------- Auto or ON

So as you can see, the universal LNB is better than the Standard in that: It covers more frequency. This allows you to receive channels from Atlantic satellites that utilize thouse lower frequencies.

3) What is the difference between:STAB HH 100 Motor and DiseqC 1.2 HH

STAB HH100 and Satcontrol SM3D12 use both DiSEqC 1.2 and USALS (AKA DiSEqC 1.3)
While Motech uses only DiSEqC 1.2

USALS allows you to move the dish to the satellite much easier by just entering your Long/Latitude for your location and the motor will move and stop automatically (active response)

DiSEqC 1.2 is a PASSIVE. You have to move the dish manually east/west until you find the satellite.

Anyone else can explain this better maybe?
