Please Note:
1. Analog TV needs a digital converter box first(please search "digital converter box for analog tv" if need be). For flatscreen HDTV, please go through your TV manual to make sure your TV comes with built-in tuner for receiving OTA(over-the-air) broadcast and HD signals or else it will not be able to receive and watch HD channels.
2. Antenna reception capacity depends on various conditions(the distance from your home to transmitting towers, your surroundings and so on). If you can not get enough channels or clear picture, we recommend trying the followings:
1) Please make sure the antenna is correctly connected to your television or 3rd part HD receiver, and having set the tuner mode to "Antenna" or "Air" in the TV's setup menu.
2) Placing the antenna higher or close to/in a window may result in better reception, always re-scan for channels afterwards.
3) Test with and without the amplifier and re-scan afterwards.
