BIZARRE BIZARRE AS IT IS

Here I would like to do justice to Philips, this is my story, I installed this signal amplifier to the arrival of the distribution cable with a catastrophic result (interference to TV) like other buyers so I removed the amp with the feeling of buying a wrong product to store in a drawer!
Two weeks later, after a visit of the cable operator to check the signal cable and the arrival of the confirmation that the problem of weak signal for HD is in the internal wiring (the TV is 20 meters from the finish with multiple recessed fittings), I decided to place the amp just before the decoder in the room, and the result is good, the signal near zero is now sufficient for HD.
Odd that the first installation was bad and the Moving amp gave a completely different result. A Meditation !!
