The antennae has to be fitted by the provided adaptor since, it's made for PAL broadcast, now with the RCA cables, the solution is to buy the ones with right angles, but this are more costly and can only be purchased in a specialty audio shop.
Check out the bracket,and measure it, even without mounting it,and creating a hole to loop in the cables,will make it impossible for one to manipulate it after it gets mounted,however, with a spacer, problem is easily solved.BTW, the bracket support is good and seemingly sturdy (check put it's size and make,hence the stability), that is if one is willing to add a little more so that no hassle in the future will occur.
The main problem really is the antenane and the HDMI cable.
