Range problem

First of all, the reason why I use the radio set. Our flat-screen TV is equipped with unfortunately very poor speakers. However, the stereo is on the other side of a double-leaf door (distance about 3 meters). Here I wanted to move but no cable bridge the short distance by radio.

Transmitters and receivers make first case seems robust, network equipment, antennas, cables, instructions, everything. The installation is done quickly. Then go the problems start:

If the transmitter is mounted to close to the TV, the screen layout is severely disrupted. The same applies if the transmission cable TV too close to the transmitter runs on aerial cables. Also disturbing some of the transmission channels per se to receive the television picture.

If you have found a place for the equipment, it takes despite the short distance of three meters for some time until you have adjusted the antenna of the device so that it roars little (!). A noise-free transmission is definitely not possible. This leaves just a little doubt about the quality, because it is after all, only three meters distance and a wooden door, which must be overcome.

Unfortunately, my expectations are not met on the set.
