I'm going to add a used HR21 to my account. I currently have a Swm Dish with enough inputs to add this receiver. Do I need a B Band Converter to the HR21?
You said you have a "SWM dish with enough inputs".
The SWM dish only has one output that connects to a SWM splitter if more than one receiver is connected..
Is this what you meant?
Yes, I have a SWM Dish and two Green Swm 4 port Splitters. I know my current SWM dish will only support 8 tuners, and I still have not used all 8 possible tuners on the SWM to support the new DVR.
