I got this to do fairly close interviews no more than 5-20 feet away. So far, no static at these distances. However, I did a little test in my backyard and walked about 100 feet away. At about the 40' distance, I started to get some static that got worse as I went up to 100' away.  Not a constant static, but enough to keep me close (FYI I have lots of phone lines and power lines going over my yard which may have caused the static).
