If you are using an antenna (not cable or satellite), here are a few tips that might help:
If you have one of those compact indoor antennas – at lot of the antennas that are promoted as “HDTV” antennas – it has very poor performance in receiving VHF television stations, like KLRN-DT. All the rest of the DTV stations (for now) broadcast in the UHF band and those smaller antennas may work just fine on UHF but are not satisfactory for VHF. At the very least, you need an all-band antenna (VHF+UHF).
If you live outside San Antonio, you may need an outdoor antenna to receive our signal. When the FCC calculates DTV coverage, their formula assumes that the receiver has an all-band outdoor antenna mounted on a 30’ mast. Of course many people would have difficulty installing such an antenna.
If you live inside the city, you might try to receive our signal using a basic set of “rabbit ears” – nothing fancy, just the two telescoping rods. You’ll need to experiment with the orientation of the rods to get the maximum signal level – and there should be a signal strength indicator in your DTV converter box. Look in the Menu for that display.
We'll keep posting more information as we move towards the June 12 transition, but you'll find much more on our DTV site at klrn.org/dtv.
