I have a Terk amplified "indoor" antenna up in the attic. The feed runs directly to a wall jack in my living room. The Terk has it's own powered amplifier; one end connects to the wall jack, the other end connects to the TV/DVR, etc. Last night I connected the output from the amp to the "INPUT" of an RCA 10db 4-port signal amplifier. I ran the outputs to my TV, DVR+, AVR (for FM). I got an immediate signal increase for the weakest channels. Is there any danger of overloading my TV or DVR on the stronger channels?
