I want to watch Hispasat, but my geography at home says otherwise. Is there any low budget way to bring FTA on the road, so to speak? I could drive up to the top of a ridge and have all the Eastern sky I wanted. What I'm wondering about is how to power a receiver? I know nothing about inverters nor the practicality of going out for a Sunday drive to watch Hispasat, but I suspect some of you are mobile, so tell me, how would you do it?
