hai...i'm doing my project using my pt2272 and pt2262 in the wireless project...the problem is,the range in the theory that i read is 10m. but,after assemble the component and i had it tested, it range goes only 10cm. and for my project, i had to increase the range above 10m. so, how can i amplify the range or increase the range. can u please give me some idea about it..

i used 8cm length for the antenna. so in order to increase the range, we must increase the antenna length?? is that u mean??

I think it has to do with wave length

A photo of your setup is great. Anyway a fast check.... the transmitter and receiver power supply, is using adapter or battery?

According to the User's manual on http://www.cytron.com.my/datasheet/WirelessDevice/RF_TX_User%27s_Manual.pdf and http://www.cytron.com.my/datasheet/WirelessDevice/RF_RX_User%27s_Manual.pdf, the antenna length of the 315MHz Transmitter and Receiver must be at 24cm, while the 433MHz at 18cm. Hope this helps.
