DNS = Distant Network Service. Pay option via DirecTV for either NY, East Coast or LA, West Coast major network feeds via your satellite service. Includes PBS, ABC, CBS, NBC, Fox, CW located between channel 388 and 399.Not exactly...You must apply for DNS stating that your account is a mobile plan using an online form. No requirement that antenna be permanently mounted to anything. You will get either East or West coast feed, not both.Do not expect much help at the AT&T store. With joint AT&T DirecTV billing you get a $10.00 savings. With an RV account you can suspend it up to two times a year...so they say. Which should entail no charges while suspended. With DirecTV dome antennas you can not receive HD programming; only SD.
No experience with Dish network or offerings.Portable setups are an economical solution that with practice can be setup for use in about 10 to 15 minutes and you can more readily avoid trees.
You may purchase DirecTV equipment but when registered with them for service, they treat like leased property (the card).
