I'm trying to split the line coming out of a Terk HDTVa OTA antenna. Sounds simple.... Without splitting I'm getting 95-100% on all channels that I care about (as reported by my Tivax digital TV converter box).
First I tried to use a basic 3-way splitter/combiner - as soon as I added the second output line the signal dropped to near zero. I did notice there is a ground screw on the splitter but I did not use it.
Second I tried to use a nexxtech TV/FM 4-way distribution amplifier I got from The Source (Radio shack) for $40. When I added the second line, most stations dropped from 100% to around 40%. The specs on the amplifier say 10 dB gain, output capability 23 dBmv, 50-900 MHz bandwidth.
I'd be happy with a 75% signal strength on each line. Any suggestions would be greatly appreciated !
BTW - the Terk Antenna has a "power injector" on the line out - not sure if this is just a fancy name for an amplifier...
