But a 100W inverter that plugs into a cigarette lighter is only $24 or less
at Walmart. That is much less than you would pay compared to trying to find
a 12v rotator system. I had similar designs for 12v rotator systems, but
just got lazy and realized it is easier to simply use these cheap inverters
that are 95% efficient and just use whatever I need in the car for playing
ham radio wether it is 12v or 115v, dosn't matter.
Though watch for RFI from the inverter?
