Take your receiver(s) from home. No additional cost.
As for dish? Go online to places like solidsignal.com and pick a package that works with your receiver. Cost around 200 dollars. There are smart phone apps like dishpointerpro to aid in finding an open spot. There are dozens of gadgets from 10 dollar beepers that are worthless to 500 dollar dedicated tools to fine tune the dish. I personally use three things. Dish pointer to find the open spot. Align A Site to do the basic alighment, and the receiver signal meters to find the best signal.
