I have a Terk set top antenna.
I moved it upstairs and routed it through my existing cable coax wiring to get to the TV and now I can only receive 1 station. It has a small booster connected to the antenna and that is on.
When it was next to the TV (6' coax directly connected from TV to antenna), all stations were fine except channel 8. I had to raise the rabbit ears to get 8.
Now that it is upstairs (50+' of coax?), I can ONLY get channel WFAA 8. And my TV says that one is 97%. The other channels are 0%
