     If it reradiates noise why not reradiating the signal you want to 
receive as well thus S/N remains constant.
How does the unused antenna know noise from signal?
    However, It can reradiate everything it receives and change your 
radiation pattern thus reducing the weak signal in some cases. It may also 
change the impedance of the connected antenna and perhaps its resonant 
frequency if it is close enough. I think the noise thing is most likely an 
observation someone made and noticed a reduction in S/N and concluded the 
noise increased while it was really change in radiation pattern reducing 
the received signal.
