TV antenna amplifier (optional)
AKA masthead preamplifier or booster, it runs a short piece of coax cable from the antenna output to the preamplifier input connection labeled "ANT input".
Power inserter (optional)
A power inserter is used to back feed power to the distribution amplifier through one of the RF output ports. This allows the distribution amplifier to be mounted at a location where power is not available. The output port that is used to back feed power is usually marked as RF Out/DC In or something similar. It is important that if the power inserter is installed correctly. The side marked “To Amp” should never be connected to the TV. This port will have 12V DC on it, and it is possible to damage your TV.
Coaxial Cable Splitter (optional)
It splits a coaxial cable signal source (cable/satellite/antenna) to multiple destinations. Connect the cable from the antenna to the input port, and connect the cable from the output port to the TV.
After all the connection is done, do the following steps to scan the channels.
1. Set up your television:
- Using your television's setup menu (consult your owner's manual for exact procedures), set your Input to either "Antenna" or "Air."
- Some televisions have multiple inputs: make sure you're setting the correct input during this procedure. If you also have cable television inputs, you can set one input to be cable, and the other to be the antenna input.
2. Adjust your antenna:
- Scan through the channels with your television tuner to see what channels are within range. If you see a fuzzy picture, try to orientate the antenna to see if the channel can be any clearer.
- For digital television, you may have special menu options for a full scan and a "manual scan." To optimize your antenna placement, you must do a full scan every time you change the position of the antenna. Write down all the settings, do a full scan, and count the number of channels found each time. Then use the setting which has the optimal result as final setting.
