Dish Network Tailgater for RV Direct tv does not or did not offer a monthly pay as you go service, so we went with Dish.
If you get any system, practice with it at home before you go so you know how it performs.
Use the Dishpointer site to view any campsite ahead of time. It will give you a good idea of reception possibilities. My 211k use 110 and 119 sats. Just place the curser on the any campsite in the park to see where the best reception might be. It tells you distance needed for trees to clearly view the sats you need.
https://www.dishpointer.com/ You need a clear view of the southwest sky. Sometimes it happens, sometimes the dense tall trees don't allow it. The two state parks that we regularly frequent do not offer reception so we only activate our system when we long term vacation somewhere else.
You can pay a 'one time activation fee' of $40 or so for DVR service. You just need to add a hard drive to the 211K receiver.
The 211k recvr has a constant 110v power draw even when its off. Just being plugged in on standby draws 22watts, fully running is approx. 50w. If you boondock, you have to run it off an inverter of some kind which also uses some 12v power to operate.
It takes about 10 mns to boot it up when you first turn it on and after you turn the recvr off and unplug it. If you leave it on standby 24 hrs while boondocking then it will eat up too much 12v power off a standard battery bank in a class C, you have to turn it on/off.
The Tailgater antenna uses a single coax wire that supplies a sat signal as well as 12v power. The antenna needs 12v power to change the direction between multiple satellites that the system uses. The antenna spins within its plastic housing . I have used 100 ft of coax to find a clear sat view with no problems for reception.
If you ever boondock, then you have to run a small 150w plug in inverter. I use a Samlex PSW
Samlex 150w PSW Inverter It has a low voltage alarm built in to the inverter, just in case you have a heart condition.
While camping , the alarm sounded when the antenna motor was spinning to locate a satellite as I attempted to change channels.
I did not know this and it scared the @#%& out of me and my sleeping family when the 9000 decibel alarm sounded at midnite when I changed channels after watching tv for 2 hours. My DW jumped up and screamed at me and my dog attacked me with her Fox Hound howl. I now hook it up to a separate AGM battery that I carry just for that inverter and 211k. I don't know which was worse, the alarm or the two of them ganging up on me. They work as a pair. :B
