I live 9.5 miles West of Carter Mountain. My outdoor roof antenna is properly aimed at 134 degrees (magn). I have no problems with any Charlottesville channels except WCAV 19 HD-1 and HD-3 which are virtually unwatchable (occasionally 1 or 2 bars). However Channel 19 HD-2 shows a steady signal strength of 5 bars. I realize that Channel 19 uses a directional antenna and I may be in a null, but why does the HD-2 come in stronger than the HD-1? Thanks.
