I have one (two, actually, that transmit to one base station) that reliably transmitted from my bulb frames to my former house, a distance of about 140 feet. I got this from a catalog called "Wind and Weather" (I think) but the instrument is made in Portland by, I seem to remember, Oregon Scientific. I'm sorry, I can't find it at the moment, having recently moved--I wish I had it set up, but I don't know where I packed it. The thermometers and the base unit are battery-powered.
