I have a DB-4 antenna to pick up local channels connected to my 942 DVR. Depending on which way I turn the antenna, some local stations come in better than others. If I want local CBS, I'll point it one way, if ABC, then turn it a bit and so on. Since I can pick up all the stations without breaking up if I point the antenna a certain way, isn't there a way to get them all to come in without breaking up without having to turn the antenna for the channel I want to watch? A second antenna joined with a splitter? My zip is 33609.
