Xbee 900mhz Home Automation project

Hi im working on a Home Automation project, and for the communication im using two Xbee pro 900mhz

And im using this antenna:

However i can only get an inconsistent range of about 1 meter, which seems odd to me and no matter what i try it stays the same or becomes worse. I am completely out of ideas and cant find a solution. Without this working i cant continue my project.
So i was wondering if any of you have any ideas on how to fix this (if fixable)

Thanks in Advance !!
