FTA (free to air satellite)on your truck
 

I see some trucks have satellite antennas on the back.Are these usually subscription satellite systems or FTAs?
I plan on installing an FTA in the truck.The package costs about $200 with a 20inch dish.I used to be a cable guy for comcast and so this is something I will be doing myself.I know I will be limited to ESPN and all the major broadcast newtorks but how is the Free To Air satellite working for you?Any snow screens in certain areas?
