How to Mount an Antenna to the Roof

An external antenna provides free television because it receives TV signals from broadcast towers placed in cities by the local TV stations.

Take safety procedures seriously when mounting an antenna to a roof.Take safety procedures seriously when mounting an antenna to a roof.
The antenna can be mounted on the roof so it has an unobstructed view of the horizon -- it can then be aimed so as to face the direction where the broadcast towers are located. You can mount an antenna to a roof a number of ways. A few tools found in most homes and some supplies from a hardware store will be needed.

Stand the antenna's bracket on the roof where there is an unobstructed view of the horizon. Screw the bracket into the roof with wood screws using the Phillips screwdriver. Apply silicone sealant to the screws so that they are covered and the holes they have created in the roof protected from the elements. Let the silicone sealant set for an hour before proceeding. Insert the pole at the bottom of the antenna into the top of the bracket. Rotate the rods of the antenna so they are facing in the general direction of the local TV broadcasting towers. Tighten the screws at the top of the bracket with a Torx screwdriver. A coaxial cable can now be connected to the connection on the antenna's base and run into the house to connect to the TV.

Stand the antenna tripod on the roof where there is a clear view of the horizon. Place cinder blocks against both sides of the legs of the tripod. Loosen the screws on the collar at the top of the tripod with a Torx screwdriver. Insert the antenna's bottom pole into the hole at the top of the tripod. Rotate the rods of the antenna so they are facing in the general direction of the local TV broadcasting towers. Tighten the screws on the collar. Attach a coaxial cable to the connection on the base of the antenna and then run it into the house and connect it to the "Ant" input on the TV.

Place the mounting plate attached to the antenna bracket against an air duct on the roof -- the air duct should have an unobstructed view of the horizon. Run the mounting cables around the air duct and through the bracket. Screw a locking plate to one end of each of the cables with metal screws and the Phillips screwdriver. Screw the other end of the cables to the other end of the locking plate with metal screws and the Phillips screwdriver. Place the pole at the bottom of the antenna through the groove at the top of the mounting plate. Push the antenna down into the groove until it comes to the bottom of the plate. Rotate the rods of the antenna so they are facing in the direction of the local TV broadcast towers. Tighten the set screws surrounding the top of the plate with the Torx screwdriver. A coaxial cable can now be attached to the connection on the base of the antenna and then run into the house and connected to the "Ant" input on the TV.
