622 hookup

[kaufmja]

I have a RV with an winegard RM-4600 satellite dish(with only one LNB output)
I want to hookup a vip622 DVR dual rcvr to one TV. I have Dish network
What do I need to do to hookup the two rcvr inputs using the one cable from the antenna?
I have read that I must change the LNB on the antenna too a dual LNB and run a second cable and hookup each cable to a rcvr input.This is dificult to do.
Is there another way to use just one cable to run one tv ,but have the capability to record two channels on the DVR?
What is the pyhsical characteristics of the dish signal ?

The 4600 appears to use a Directv box type LNB instead of DISH's Dtube LNB so your only alternative is get a DUAL LNB and run 2 cables into the back of the 622
