ASK module extended range idea?

[Danesh_SA]

Dear friends,
Im working on new project that use 4 ASK receiver and one ASK transmitter , just for ON/OFF relay,and im using PT2262 in transmitter ,PT2272 in receivers
but the operation range is too short.
i think about how to extend the range of them , and one of my idea is to use repeater between transmitter and receivers,
like this:
Transmitter ----->Repeater---->Receiver(1)
                                       ---->Receiver(2)
                                       ---->Receiver(3)
                                       ---->Receiver(4)
1-Does it works?
2-if i want to implement it, just need to connect DATA pin reciever to DATA pin transmitter and it works as repeater?or i should use a couple of PT decoder/encder?

What range are you seeking ? What is the data rate ?

Are you using an external antenna ?

There are protocol modes that using very low power can span 1000's of kilometers -
