Using dish hopper from home while on the road

It is my understanding that a Dish Pro Plus (DPP) LNB is required. Between the antenna and the Hopper you will install the Solo Node (Google that) and then just move the Hopper/Joey between the house and RV.

What is a solo node? Can I use an older a Dish 500 dish? Or must I use the new had one?

I do it all the time. Works very well. Even brought a Joey so bedroom could watch different channels. You will have to get a solo node for the hookup.
