1. Connect the coax download from the antenna to the power 

injector’s 

ANT

 jack.

2.

If your TV has an F-connector

, connect the coax from the power 

injector to your TV’s VHF/UHF 75-ohm F-connector.

If your TV has screw terminals for VHF/UHF connection

, connect 

a 75-to-300 ohm transformer (not supplied) between the power 
injector and the VHF/UHF terminals.

If your TV has a 75-ohm VHF connection and a 300-ohm UHF 
connection

, connect a signal splitter (not supplied) between the 

power injector and the TV’s VHF/UHF connections.

3. Insert the AC adapter’s small plug into the power injector’s 

DC 12V

 jack. Plug the adapter into a standard AC outlet. The 

power injector’s LED lights to indicate proper connection.

Many do-it-yourself and professional antenna installers are injured or 
killed each year by electric shock, because they fail to recognize 
overhead wires as being potentially lethal. Touching any part of the 
antenna mast or guy wire to these overhead wires is the same as 
touching the wires with your bare hand. A very serious shock is 
almost sure to result when contacting an electrical wire. In the case 
of primary wires on the top of poles, the shock is like being struck by 
a bolt of lightning. Many power wires are within 20–25 feet of the 
ground and can easily be touched by an antenna and mast.

 

  Select an antenna site away from all overhead wires.

Do not try to guess which overhead wires carry high voltage. If 
you notice anything making contact with the overhead wires, call 
the power company to have it removed safely.

  Get help from a qualified professional when removing the old 

antenna if there is any doubt of clearing overhead wires.

  Never install an antenna when it is windy.

  Do all assembly work on the ground, then raise the antenna.

  Make sure the antenna mast downlead cable is connected to 

suitable lightning arrestors.

  Make sure the installation is secure. Use plenty of guy wires and 

new hardware.
