I am currently investigating the use of radio frequency identification for livestock control. Would the fence work as an antenna?
It would not be possible to use the fence as an antenna. An RFID antenna must be able to radiate a signal at a specific frequency and control changes in the waves that communicate commands to readers, and it must be able to receive a signal at a precise frequency. There would be no way to enable a chainlink or other type of fence to do this. Moreover, the read range would be short, so you would only be able to read tags on animals near the fence. Most farmers put readers at specific choke points, such as at the gates through which animals pass on their way to the field. If an animal's specific tag were interrogated as it passed such a reader, you could know that it was in the field.
