I've had good results running my HD73 rotor, using a 300W inverter, purchased from a big-box store discounter, for about $40.
I bought it initially to run a 13" TV with a built-in VCR in the car for my harmonics when on long trips. It uses a lot more wattage (140 watts) than the rotor does and I've never had an issue with it cutting out or blowing a fuse.

Hello All, I have a old Alliance HD-73 azimuth rotor and a Kenpro KR-500 elevation rotor.At present time I cant set up at my home on a permanent basis but would like to run a setup on a spare utility trailer that I can work from in a field behind my house...problem is no A/C power.....I am curious what size a/c inverter would be recommended for this type of load......I'm currently taking the ARRL Analog Electronics course and am learning how to figure such things but I'm not comfortable making calculations for a real world situation that involves motors at this time. I am also aware that you have to be carefull with what "quality" of inverter you choose.....some of the cheaper units you buy at discount places are WAY overrated.....I'm looking for something thats a good VALUE....Thanks
