Installing a TV antenna is a bit more challenging since the conversion to digital TV signal only in June 2009. Fringe area reception for analogue TV reception may not be possible for digital signals. Still, the basic installation of an antenna remains the same other than the need for a converter box if the signal is not being fed to a digital receiver.
Select a location as high as possible without obstructions in the direction of the TV broadcast you wish to receive. Location in a valley may require erecting a tower or simply abandoning the antenna hookup and using an alternative cable or satellite signal service.
Carefully erect antenna mounting hardware that came with your purchased antenna to the highest location possible. If a roof peak is selected, for example, tie off whatever ladder or scaffolding is used so the installation is done safely.
Use "F connector" adaptors to connect the antenna feed cable to the coaxial or "RG-6" cable placed down the side of the house with screw-in fasteners or heavy-duty 9/16-inch staples depending on the type of exterior siding of your home.
Drill a 1/2-inch hole at the entry point of the exterior wall nearest the receiver and screen to be used where there is no chance of hitting any electrical wiring, water pipe or other obstruction. Put insulating material between the cable and wall surface to secure the opening once enough cable is pushed through the wall to reach the receiver. Feed the coaxial cable through the hole and connect the end to a converter box or directly to a digital receiver with "F-connectors" available at any electronics outlet.
With someone monitoring the digital receiver, slowly rotate the antenna until the best sound and picture is received and fix the antenna in that position. (An alternative solution could include an electric rotator mount for the antenna so that more than one direction of broadcast signal could be received adequately.)
Any work at altitude includes the danger of falling. Secure scaffolding and ladders and have a buddy on hand to make sure no accidents occur.
