New station, very low stroke number

[Gianfran]

I connected to ground the main controller and now i reduced a lot the noise, so I can get an higher amplification, as shown on the screenshot:

   

Now I have some question in order to improve the quality of my station:

1) Why there is a big difference between channel A and channel B? It's normal?
2) I mounted the amplifier in the same pole of antenna TV, it can generate noise?
3) The amplifier is mounted vertically, with rod ferrite antennas at 90 degrees. It's good in this way or I have to mount it horizontally?
4) To link the amplifier to the controller I use an unshielded ethernet cable, this can create interference to amplifier if it is near the ferrite rods?

Thanks for your patience!!
