Following in Numericable, I have 2 TVs with unwanted signal loss with the most chance long.Par cable, I fell on the amp KONIG ANT AMP PRO30A. Since moving my life has changed! Already, unpacking, although made in China, this device is far from hollow inside, you really guess impeccable build quality. After connecting (30 Seconds), all channels are received to perfection and without adjustment. Attention to Numericable, use this model with back circuit. In short, a product to recommend.
