I had a good reception TNT (without amplification), but who bought a USB Tuner for PC, used in parallel with my TV, I had to split the antenna signal into two, and suddenly the signal has become insufficient. So I tried the amp in question to both divide and amplify the signal. It proved useless. A low gain, the signal was insufficient. By increasing the gain I had a sufficient intensity signal, but the signal quality was so degraded (my TV can display these two parameters) that it was impossible to have a picture on some channels.
I bought a professional grade receiver of another brand (much more expensive) that gives me satisfaction. In particular, this new amp to adjust the gain of each output independently, which provides considerable comfort.
