Do what I did,We have direct tv and I didn't want to run the cable underground,I bought an extra dish off craigslist and mounted on my roof and set it up,As long as you have the receiver it won't cost any extra,I use the one for my motorhome all winter in the garage
Last year I bought a Miller Furnace from a Mobile Home off Craigslist,It's hot air and mine runs on Kerosene but they also make them for propane,I live in Pa and in the winter I can work out in my garage in just a flannel shirt,Best move I made
