Does anyone know of a particular antenna or amplifier that is superior to others with digital OTA broadcasts? I have an old TV antenna in my attic with a radio shack amplifier that works great on all stations except channel 26-1 out of Green Bay, which is digital channel number 41. Others higher and lower in number almost always have a strong signal, but channel 26-1 often pixelates or indicates "no signal" using my Hughes Direct TV box. Any thoughts on this??
