Antenna bad reception
 

My N900's antenna is working very bad, not in every call, but very often.
The signal is full, 3g,2.5g,2g, but this changes nothing.
I've open the device with the level 1-2 guide and i've unmount the antenna two-three times.

My questions are:
is there a method to test my antenna?
is it possibile that is a software-related problem?
did I have broke something by opening my device?
where can I buy a new antenna?

thanks!

I was having similar issues for the last 5 days, I always had full signal at home. then suddenly something changed and I couldn't get any signal indoors.
took me a few days to realise what I had done, I had swapped batteries with another n900 and this battery was behaving in an odd way (it would go off completely when it actually measured a 50% charge). Today I swapped back to my old battery and guess what ? full network coverage again.
