Connect the co-ax cable from your digital OTA source (rabbit ears or whatever) to the input co-ax connection on your old digital-to-analog converter. Then use a short piece of co-ax cable to connect the output co-ax connection of the converter to the input co-ax connection of your old analog VHS recorder. Finally, use RCA connectors to hook the VHS output to your 55" TV just as you did before.
Now, connect the co-ax cable from the cable co. to the co-ax input of the
55" TV and you're in business.No splitters; no A-B boxes.
You will be able to record only OTA with this setup. If you want to record OTA and cable you will need a splitter. Post again and all will be revealed to you.
