Yet the cable brought a clear improvement!
Previously, I had an antenna cable from Oehlbach with 4 stars in action. This cable was significantly shorter - and dated back to the early days of HDTV era.
The signal quality was indeed always high (at 100% close), although it came from and to image distortion as the signal strength always was only 30%.
Now with the cable of In-acoustics, the signal strength of 30% (red) to over 60% (yellow) has increased.
The signal strength has doubled and at a very good P / L ratio!
A technically similar cable of Oehlbach costs about 100, - more.
Only the Oehlbach Transmission Ultra 1000 for 249, - I would like to test whether it brings even more.
Whether that is worth a more than 200 charge is questionable.
Therefore, absolute recommendation for the cable of In-acoustics!
