Answer 1

12.207 GHz is the frequency the satellite broadcasts on.  Most satellite dishes have a converter on them, that convert Ku band (12 GHz) down to L band (950 MHz - 2150 MHz).  Sounds like your digibox will connect directly to the satellite dish.  The question is, what is the output of your digibox?  Chances are, the digibox has RCA (line out) jacks, that connect directly to the tv, without modulation.

176000 KHz = 176 MHz, which, in North America, is 'channel 7' on an NTSC analog tv.

It sounds like you need a downconverter, unless your samsung can receive frequencies 69 times higher than its present default.

Answer 2

176,000 kHz = 176 MHz = 0.176 GHz  That's about TV channel 7.

12.207 GHz is Ku band satellite (much higher).  You need a separate reciever fot this, a normal TV set won't do it.
