TV36
NOTE: Grounding the antenna and mast provides lightning protection for the antenna and your TV set.
All outdoor antenna installations should be properly grounded. To effectively protect the installation, the coaxial cable(s) should be grounded before they enter the house. The grounding of the coaxial cable is made using a “ground block” and copper wire (not supplied). For information and the materials needed to ground your antenna installation, visit your local electronics store.
If you are not sure how to install the grounding block and rod, please consult your local retailer or TERK’S Technical Support Department at
An outside wall of your home is also an easy and convenient mounting place, but the wall and fasteners that you use must be strong enough to support the antenna in high winds. Ensure that the brackets are securely fastened to a solid part of your wall.
1.Space the mounting brackets on an exterior wall – be sure to clear roof eaves or any other obstacles.
2.Secure the brackets to the wall using the 4 lag screws.
3.Insert the mast between the saddles and secure with the nuts and bolts.
Tripod Mount (not included) - Used on peaked and flat roofs Suggested height limitation: 10 feet above the rooftop. Installation involving a tripod mount and a mast should be guyed if the mast is ten feet or more. The tripod mount must be securely anchored to the roof as should the guy wires. Apply roofing compound around the base of the brackets, screws and eyebolts to

1.Mount the 75 ohm grounding block or discharge unit as close as possible to where the downlead enters the house.
2.The ground wires for both the mast and the downlead should be copper or aluminum wire, number eight (8) or larger.
3.The downlead wire from the antenna to the antenna grounding block or discharge unit and the mast ground wire should be secured to the house with
NOTE: In the case of a “ground up” antenna installation, it may not be necessary to ground the mast if the mast extends four or more feet into the ground. Consult a TV serviceman for the proper depth in your location.
