need help i am designing a proximity indicator using an encoder HT12E with a T5-434 transmitter and a decoder HT12D with a R5-434 reciever the only problem is that i don't know how to reduce the distance to be a few meter cause the project requires a distance of few meters but i am still transmitting and recieving above 500meter help needed.

Reduce the transmitter power, or attenuate the signal.

You realise that things other than distance will affect the received signal strength, right?
