Other options for securing a cardboard ring are:
Using a hole punch, punch a couple of holes in the cardboard ring at 180 degrees and thread some string through the holes and fasten the string to the top and bottom mounting rails (if you have them), or around the OTA.
You could also add (glue/staple) 3 tabs or ears that stick out from the cardboard mounting ring and then tie some string around the OTA that passes over the top of these tabs or ears, thus securing the ring to the OTA.
