A client asked me about them on a big reno we’re doing. I always assumed they were largely hokum (sp?). Can’t find much research on the web on the subject. Seems to be “can’t hurt.”
THe house is just outside Portland ME. Plenty of trees around, tallest structure for several hundred feet, but it’s also hilly, reasonably high housing density, not in a field in the middle of nothing else above shrub height. Is it worth the effort to install a system? Anyone actually seen any research?
