Help bad signal :(

[Shavkat]

I will try to change that!
But i think i understand why I'm having so bad signal!
If you look to upper right corner in back of Titan, there is small black circle.
If i open that circle and contact any metal wire, signal goes ok (even in my room)
And when i remove wire signal goes down!?
What do you think, is it RadioBlock or what?
And thanks for help hotbyz168
