"The Channel Master is good for only 20 miles reception. Bad deal."
FM broadcasting is limited to line of sight, so far as I know, at least for high quality audio reception. Which means that you can only receive what is above the horizon. At sea level, the horizon is about 4-5 miles away, or so the internet tells me. At 330ft above sea level, the horizon line is about 22 miles away. Furthermore, good reception is dependent upon many things other than distance, like bandwidth of the antenna, directionality, etc. If you live much more than 20 miles from the nearest high quality FM station, then I hope you are in a high rise building, but I don't see why you bash the Channel Master and the Magnum Dynalab on the basis of their range, which is a kind of meaningless figure anyway.
