The HDA-10 is an all purpose Amplifier for home and small distribution systems that is great for driving a couple of TV's from Antenna, with a total length from Antenna to TV of about 120 feet, place the Amp before the input of the Splitter, indoors, as close to the antenna feed in (as it enters the home or premise) as possible. The high output capability provides a lower distortion than economy models while maintaining quality and reliability for the most sophisticated applications.
When you go from just one TV off of an Antenna to two or three, it does make a difference. So run each cable line individually to each TV set from a common splitter location and place this Amplifier before the input to Balance the levels just right!
