need help understanding what is wrong with the reception of one
channel. i have an old metal antenna on the house that works great for the strong local signals. years ago i added a small antenna that was designed to pull in one particular local channel. it is installed on the same pole, and plugs into a small box also on the pole that acts as a splitter i guess. anyway, regardless of whether i am running the signal into the vcr or the tv, all the powerful channels come in fine. however, this other one, channel 13 (Hmmm...) doesn't come in well unless i disconnect the coax from the tv, then very gently touch it to the connection on the back of the tv. the improvement is dramatic, but i'll be damned if i'm gonna watch tv this way. i don't understand why the same connection works great for the other channels, but not for this one. i have tried changing out the cable, using splitters, not using splitter, directly from wall, from vcr, etc. it never seems to come in unless i am holding the cable connection to the connector on the tv in this very specific way. what's going on? i know this station used to come in better, but now its crap. help. anyone? |
