Xbee antennas

Trying to sort out an external antenna for the Xbee modules on the F9P. If you’re running 900 MHz should you be looking for a 916 or 868 center frequency?

heres what i use with the freewave kits that come with Swiftnav Piksi Multi. It has range of 870-960. Not sure how critical antenna selection is. :slightly_smiling_face:


I was looking at these, nice long cable and seems to be low loss. Just have them so I can move the radio between units

range is not even to 900? On the ones i use I just build my own cable and put an SMA female panel mount connector on that end. And then just screw antenna to it :thinking:

I use 868mhz xbee radios, and I built a dipole groundplane antenna for the base to get long distance, as we only are allowed to send 25mW in Europe.

Made from a chassis sma connector and some copper wire. I ordered an antenna analyzer to calibrate it to exactly the right frequency. Most of cheap antennas are off frequency and will not get maximum range

It looks to me like most 900 MHz radios like the digi or freewave in North America have about a 915 MHz center.
