Extended cable between box and antenna

[tobydude]

Hi.
I extended the cable between the box and the antanna with 15 m.
Will the signal in to the box fade with 15 m extension?

Depends on the cable type, there will be some difference but it shouldnt be to much.  As you have already extended the cable you should soon see

It is recommended to use a cable with an impedance of 50 ohms and that is not steel
