Attenna to use with a Xtend 900 1w

I'm working on a project where we are trying to offload information from a bicycle live while we ride around.  Other people have already bought two of the Xtend900 1W RPSMA,  but when testing with some cheap universal antennas we've only been able to get 200-300 foot range.  I'm wondering if anyone here has used these modules before and know what type of antenna to use to get some more range from them.   None of us have found much information on these modules with different antennas and the effect on ranges.
