hello iran, you need to know what type of receiver and how many disec tones you have. in your set up you can set up a 4 input 1 out multyswitch. this will be good toe one person and one receiver. is you have disec A,B,C,D then you can set up 4 satellite possions and it will run one receiver. if you are running a small appartment complex then you would need a 16 input and a 16 output to run 16 satellite receivers in a appartment complex. each lnb converter would need 4 lines a quad lnb. this devides HL,HH.VL,VH and if you make a mistake then you would have problems ralph
