An external antenna: 25cm ordinary multi-core or single-core wire line will improve its range, does not come slandered, you can solder the wire for antenna.
Above information are model specific, which are mentioned for transmitter and receiver module. We can not guarantee that you will get above model. We will send you similar specification modules. In different module, pin position may change. you will find pin specification printed on PCB. Normally these module have pins like ANT-Antenna, VCC, GND, Data.
For working with these modules you may require encoder and decoder IC
