How to buy Tunner to RF modulator?

Step 1: where is your signal source from?

From satellite or cable, wireless system? It determined which standard input tuners you need.

DVB S/S2 tuners are used for receiving satellite signals

DVB T/T2 tuners are used for receiving wireless system signals.

And DVB-C(ATSC-T/ISDB-T) tuners are used for receiving cable signals.

Step 2: how many tuners input do you need? you can 4/8/12/16/20/24. As 4tuner is in one module.

Step 3: How many RF carries output do you need? 4RF or 8RF? 

It depends on how many channels are there, what bitrate for each channel, and how many bitrates the specific modulation standard output can carry.

If you don,t know how to calculate them, please let us do it for you.

Notes: if you want to use 2 kinds of tuner as input, it also supports mix.
