Power as a truly antenna cables make a difference?

Yes, it does.
I had not believed it at first, but compared to my old Noname cheap antenna cable the difference is still on.
Although my old cable was only one meter long, I immediately noticed were the slight pixelation, small image disturbances and some bad reception at once away.
At first I had the cable receiver and the AV receiver in suspicion, but a Google search brought with the tip.
A cable is to swap to remedy the situation? An attempt was worth and is also cheaper than buying new NEN cable receiver and AV receiver. :)
It has helped and I'm happy about it.

The cable is processed excellently and is absolutely worth its price.
While it is not quite as flexible and slightly thicker than the cheap cable, but that should not really interfere well.
