Funny enough, my first NOAA image was using a log periodic TV antenna up on our tower, not at all meant for it but I don't think it did too badly, still need to try it out using a dipole and see how that does, but I've been forgetting to do it and today isn't that great weather wise. Here's an image from back in late April from NOAA-18 (iirc)

With mine (an Acer Aspire A515 I got for free from where my mom works) I get around 3 hours (according to the time remaining, although in longer use sessions at my desk I usually plug it in every hour or 2, and unplug it when its full), which is about the same as Windows thinks it is. So i would say it gets around the same battery life whether I use Windows or Linux
