Antenna for WiMe


I need help to choose and use the good antenna for my needs.

I’ve changed the default WiMe dipole antenna for two ANT24-1400 (DLINK) antenna, but it seems not to work properly.

Antenna infos :

I want to build an ad-hoc connection between 2 WiMe modules on a range of 300-400 meters.

Did someone know if only some antenna works with WiMe module, or if there are problems with the one I have choose?
