YOU ARE RIGHT! Outdoor installation is best, but ANTOP antennas can also be installed indoors or in attics. (50% strength/range is lost indoors). Simple, direct connections and installations are best. The more junctions in the installation, the higher the signal loss. Each time the signal is split (to go to another TV) signal strength is reduced, so a low-noise amplifier may be needed to help compensate for the signal reduction. ANTOP offers antennas with a built in SmartPass amplifier and all come with a built in 4G LTE Filter to reduce noise levels. Install the antenna where signal is “present”. Move the antenna to different locations until signals are found. Many times one end of the roof or room has better signal characteristics than the others.
