  • sorry, i think you are right, its 50mW

  • Very good information, thanks for that.  I know you said it was a 60mW, but the one I was looking at http://store.diydrones.com/XBee_PRO_900_extended_range_module_w_RPS...  states a 10km range and it is a 50mW.  Is this the same and I am missing something, or where do I get the more powerful version?  Also, what kind of range did you get with your transmitter and receiver, or did you just use the autopilot?

  • Here is my writeup on my experiment...

  • it depends which Xbee you are talking about. I was using the 60mW PRO 900.Any 900Mhz patch antenna would do. Just do a local search for "900Mhz patch antenna".
    The key is keeping the antenna cable as short as possible so ideally attach the Xbee directly to the back of the antenna.

  • I tested and it dropped out at the rated max range of 10km using a 14dBi patch antenna.
