The placement of the telescopic arm is not positioned as it abuts on the cables when the folds against the wall.
Unable to disassemble, change the direction of the telescopic arm folds or mount it upside down, because the system is made to be folded and unfolded by the left.
As impossible to fold it to the right, which could avoid abut the telescopic arm on the cables.
I think if you have a 46 "or more, the arm will not stumble on the cables.
Otherwise, easy installation; clear instructions; and (appearance) of the telescopic arm strength.
My screen weighs just 15Kg. I have not tested heavier.
Oh yes! Do not trust the paper plane to make the holes on the wall. Place the bracket directly to the brands of the future holes.
All the walls are not right.
Edit:
Here is a solution for smaller screens (32 ") ... connect the HDMI cables on the side ports. Most have two on the side.
Forget the antenna, even with a catch "right angle". It abuts the telescopic arm.
Personally, I just plugs A console and TV Box.
And for those with an amp, connect all your devices to HDMI on the amp and then plug the amp with a single HDMI cable to the TV.
It is a space saving and cable connecting the TV. Visually, it's beautiful and not bulky.
But it does not stick to the wall either. We still space saving of around 3/4 cm view that the cables are on the sides.
