Note 1: The number of channels you got in your area is determined by what's being broadcast in your area. Channel reception will vary depending on how far away you are from broadcast towers, and your surroundings (i.e. obstructions between you and the towers).
Note 2: The amplifier / booster can enhance the signals weakened by the obstructions between you and the towers, but can not add signals.
Note 3: We do NOT recommend to use this amplifier / booster if your house is very close to the broadcast tower and the signal is already very strong. A booster will cause self-oscillate and you may get fewer signals than without.
Note 4: The amplifier works with passive antennas and cannot work with antennas which already are amplified.
We DO offer a 90-day money back guarantee in case of this booster doesn't help.
