how big of an inverter for Direct TV
As I've mentioned on other threads, I'm looking to install an inverter to run my Direct TV components from my batteries. I asked around, called the companies, and determined that; My TV uses abo...

The OP only said "...uses 120". Maybe it's time to tell us - 120 of what? :)... And if it's not 120V, then what 120V devices do they have in total, i.e. what this inverter will have to run, including electronics?
Sorry, I thought I was clear.
Some guy at Winegard said he calculated by multiplying the volts by the amps, and came up with 120 watts for both the 'Trav'ler' dish and the SWM system add on that I had to get to make my dish work with my receiver, for a total of 240 watts for both.
That seems pretty high. I'm guessing that this is the peak usage when the dish is running it's electric motor to position itself. Don't know for sure.
Now I'm wondering if I position my dish when I have my gennies running, and shut off the power to it when I use the inverter, will the SWM system still pull 120 amps? I'm guessing not. But, even if it did, that would put my wattage at under 200, which someone said I could get away with using a 12v receptacle to power a 200 watt inverter.
