minard3, Welcome to the DTVUSA Forum. You can connect the
CECB to a Directv receiver and you don't need an A/B switch. You connect the antenna cable into the
CECB and the output of the
CECB to the antenna input on the back of the Directv receiver. To watch
OTA DTV you need to turn off the Directv receiver and use the
CECB tochange the stations for
OTA broadcasts. That should be all there is to it.
