SI4713 RF output problem

Hello, we have developed a project to transmit FM radio signals using a IC SI4713, but we believe that the problem is sometimes the IC Si4713 radiates FM signals throught the antenna and sometimes no. Why we conclude this? Because, at to put any other radio close to antenna from our device, sometimes it interfere the signal that we radiate from our device and sometimes no. However, at the testing laboratory where we have developed our project not happens that, but only at test outside laboratory. Which will be the problem? I attach an image of our device and antenna to test.
