I have a Samsung SIR-T451 digital receiver and Silver Sensor antenna that does a decent job of picking up local OTA digital signals. However, I have been using a Jensen programable antenna with built-in amplifier instead of the Silver Sensor because it generally produces a stronger signal. After some experimentation with both antennas, I believe I may get better results with the Silver Sensor if I can run it with an amplifier/booster. And after a brief search on the Radio Shack website, I managed to find only one antenna amplifier, but it was listed for "outdoor antenna" service. Will any antenna amplifier work fine with an "indoor" antenna ??? And where else (besides Radio Shack) can I shop for a stand-alone antenna amplifier ???
