15 dB distribution amplifier
I use antenna with digital converter box to analog TV for much of my viewing. From some stations, the signal will occasionally break up briefly and it shows on the on-screen signal strength scale that the converter provides. I wish to add another set to the antenna and bought a 15 dB dist. amp. Installed it immediately before the converter as a test before making any other changes. It does not shown any change in the signal strength on-screen scale whether on or off. The power-on diode lights properly. Does this seem correct? What should I expect from this test? How else to test?
