for ham radio use

unfortunatelly...if you were to use the reflector...it wouldn't be big enough for 1200Mhz.....as for using the lnb.....what you would need to do is find the oscilator in it an disable it.turn the mixer into an amplifier, and this will give you some gain at 1200Mhz.but the antenas on the board (the two silver like bands) are not tuned for 1200Mhz, so they would need remaking too.
Hope this helps....(ham radio too)

How big a dish? Why not just go helix or h/v (one part of beam in horizontal plane and the other in the vertical?) Re-engineering the tuned circuits in the LNB is not for the faint at heart. You could salvage the dish as far as using it as a reflector goes, but re-tuning the gunplexers in the head is something I'd not try.
Also a ham.

the dish is not an antenna, it's merely a reflector. The head, sometimes called LNB for low noise block is that part that receive the signal and convert it to an lower frequency that can go down the cable to the tuner.
If you are doing ham radio, the exam probably covers that.
