Make sure the multiswitch is a plus 22khz.
The 101 sat goes to the A imput.The 119 sat goes to the B imput.
Mine is not grounded but I guess you can to a water pipe or similar.
Make sure you set the ird for the oval dish...

question is this a rca system? is it the multidish system? if the answer to my questions is yes then you can connect to the drd420 ird direct the rca multidish has a bultin multiswitch and you do nont need diplexers
