Antenna problem (RTF-DATA-SAW)

[tomas]

Hi I have done PCB and soldered all components. PCB: All things working fine, signal is transmitting, and receiver part receives signal correctly. But the problem is DISTANCE... It works only in 10 cm range.. I need 10 meters minimum..

Transmitter and receiver I use: https://www.abacom-tech.com/assets/data_sheets/RTF_L-DATA-SAWuser.pdf

For antennas I'm using 17 cm wire rod (made it by myself from simple wire. I just removed isolation from wire)

Any suggestions?

It's better you try with https://www.ventor.co.in/index.php?main_page=product_info&cPath=69&products_id=287

I already bought RTF-DATA-SAW transceiver, so I need to solve issue with it ;/

Are you sure it transmits data 10 mtrs far?

 

[tomas]

I don't know, but i guess it should. Why do you think that it cannot transmit/receive long distances?

 

[jayanth.devarayanadurga]

I think it only transmits to 10 meters if the receiver is in line of sight.

I think it only transmits to 10 meters if the receiver is in line of sight.

Why? How you calculated it?
