Please note that several factors can affect your ability to receive the broadcast signal at your specific location. Objects such as tree foliage, building construction type, metal roofing materials and the physical terrain of the land all play significant roles. Aluminum or steel siding, metal lath or older plaster walls, and metal mesh under stucco all can interfere to some degree with reception indoors. It is generally assumed that there is a straight line of sight to the broadcast towers at a height of about 30 ft. in order for the up to 40-mile range ratings to be completely accurate.
