I've been through two Sat Buddies, but each failed after about 5 months. I know, I could send them in to get them repaired, but I'd prefer to buy a handful of the cheap $8 meters, so I can crush them when I'm mad and forget them when I'm in a hurry. The only downside is, I have to go up to the roof twice to do an install, because I need the cable/recievers installed so I have power on the roof (no internal betteries on the $8 meters). The meters in question require 18v in order to operate. ...well it just so happens that I've got a Milwaukee Electric hammer drill that has 18v batteries. Has anyone had success in moding their battery to supply power to a coax? If not, I'll be working on it the next few weeks.
