I am researching getting a portable sat dish to use when the roof dish is blocked by trees.

There are two "Sat In" coax connections in the utilities compartment where I assume either could be used to connect the portable sat to the Direct TV receiver.

There is only one coax connection on the back of the receiver so I assume all coax cables are tied together and that any signal from either one sat dish will find its way to the receiver without a receiver signal source change.
