No. You need the LNB to convert the 10 GHz down to around 1 GHz that's sent down the coax to the receiver. The satcan receives the 1 GHz "down converted" and demodulates it. You'll need to provide about 15V DC up the coax to power the LNB, and the satcan will usually need 12V stabilised and 5V stabilised to power it. I also used to find the output of the satcan demodulator to be a bit weedy, so I'd have an audio (or multiplex) buffer stage using a low noise op-amp (NE5534 usually), giving a bit of gain and a nice low impedance output.

Sorry what I meant was can I take the satcan out of an analog television receiver (the old set top boxes) and use it by itself with an lnb?

Yes - if you know what the pins on the satcan do!

Do most output the completely demodulated audio?

Mostly. There were a few that fed out an IF signal for further processing before demodulation

Tell us what model you have, and one of us may have the connection data for you.
