Don’t Let Your Antenna Kill You You should know about the dangers of power lines and lightning Y our set can be wrecked, you and mem¬ bers of your family can receive pain¬ ful shocks and burns, your house can be set on fire—all because of an improperly installed antenna. The main danger usually arises from the antenna’s nearness to electric power lines. For, if your antenna should fall against a live power wire, the stray current that would then be conducted through the building could take a path (such as through plumbing or heating pipes) that could elec¬ trocute or severely burn a person within and set the building on fire. What is a dangerous installation? No matter how securely attached to a firm base your antenna may seem, it is a peril if it is put up wdthin a few feet of a power line—or by means of supporting guy lines that cross a power line—or on a pole that could fall across a power line. And when an antenna near power lines is fixed to a loose or crumbling chimney, or with bolts whose threads have been stripped by over-tightening, or with inse¬ cure guy lines—then, obviously, the danger is great and immediate. While some communities have laws de¬ signed specifically to insure the safe installa¬ tion of antennas. New York City has none. But whether or not such laws exist, a serviceman should carefully observe com¬ mon-sense rules. He should make sure that the antenna clears all power lines, and that the bolts, turnbuckles and bases of attachment are secure. How about the danger from lightning? The presence of an antenna on your roof increases only slightly the chances of your building being struck—and then only be¬ cause the antenna increases the over-all height of your dwelling. Placing the arrester However, unless the lead-in conductors are enclosed in a continuous metal shield that is permanently and effectively grounded, it is wise to have a lightning arrester installed. But, if you follow the advice of the National Fire Protection Association, you will ndt have the arrester on the antenna. Such an installation may leave the set entirely without protection. The arrester should be located on the transmission line at a point near the ground, or as close to the ground as the receiver, either inside or outside the building. Next time your serviceman turns up, ask him to check this for you. 12
