Power Line & Lightning / Grounding Safety
SAFETY & WARNINGS
Note: Proper power line and grounding safety precautions should be followed for your safety.
Note: Techies Store LLC dba Range Xperts is not liable for any harm, injury, or damage resulting from the installation of and/or from natural events disasters such as storms, hurricanes, wind, and/or lightning. For your safety, read and obey all proper installation, power line, and grounding safety warnings.
BEFORE INSTALLING / SITE SELECTION
- Select a safe site to install the antenna.
- The distance between any power lines and the installation site should be at least two times the total height of the mast, tower, mount, plus the length of the antenna.. Make the separation distance away from power lines even greater, if at all possible. Since all overhead power lines look somewhat alike, consider them all dangerous and stay well away from them.
- If you have power lines in the area, call your local electric utility for assistance.
DON’T LOSE YOUR LIFE, FOLLOW THESE INSTALLATION SAFETY WARNINGS!
- WARNING: Power lines kill! A safe distance away from power lines should be at least double” the total height (including tower, mount, antenna, and mast height) plus double the length of the antenna!!
- Perform as much antenna assembly on the ground as possible.
- NEVER work alone; with two people or more, assemble antenna on the ground and use help for the mounting of antenna, tower, and/or mast.
- Ensure power line warning sticker is installed on both sides of the antenna (if any are missing or need replaced, a spare has also been included in the box).
- Check weather conditions. Be sure that it hasn't rained recently and that the lawn is not wet or muddy. Make sure that rain or thunderstorms are not predicted for the day you decide to install the antenna.
- The wind can blow the antenna into a nearby power line. Don't install or remove antennas in moderate or heavy winds.
- If using a ladder, make sure it’s made of non-conductive (non-metallic) material!
- If possible, have someone present who has been trained in electric shock first aid.
- If you’re unable or uncertain on how to install and/or mount your TV antenna, always seek the help of a professional to do this for you.
- You can lose your life if this antenna or its mast, tower, or mounting solution comes in contact with or even near a power line!
- Watch out for power line (overhead and in all directions) If the antenna, guy wire, mast, tower, or other connecting equipment comes near a power line, it can kill!
- If using guy wires, estimate the length of each wire first and make sure none can come near any power lines during erection, installation, or falling. Use the double rule, of at least double mast and tower height plus double the antenna length away.
- WARNING: Use extreme caution when installing the antenna. If the antenna or mast starts to fall, let it drop! It could have contact with an overhead power line and both the mast and antenna are conductors of electricity and power line voltages and current are lethal! Let antenna / mast fall and then call your local utility company to remove from power lines!
- If an accident or contact occurs call 911 immediately (or similar emergency line if in another country). Never touch a person that is in contact with a power line (you’ll also be electrocuted).
- If the person is free and away from the power lines and not responding, check for pulse and breathing. If not breathing, conduct CPR until medical help has arrived.
- If you’re not confident in safety, a safe installation, and/or the proximity of the power lines, contact a professional TV antenna installer to do the work for you!
- Install on a calm, no-windy day (wind can easily make things get out of hand and increases chance of touching or too close to power lines and loss of control of antenna, mast, and/or tower due to the wind forces applied on a large surface area.
- For lifting, erecting, climbing, and/or installing the antenna, look for all power lines to ensure they are a safe distance away. A safe distance away from power lines should be at least “double” the mast height plus double the length of the antenna!!
- Never use a metal ladder (these are highly conductive, thus more dangerous near power lines)!
- Even the slightest touch or even just the near proximity of antenna, mast, guy wire, or tower of a power line can kill! Never chance it!
- When on the roof, ladder, or tower, have a spotter on the ground, to help see things that you can’t.
- If you start to lose control of the antenna, mast, or other, let go and let it drop to the ground, to, as either power line contact or falling off a tall roof, ladder, or tower (even without power line contact) can all be lethal or result in a severe injury.
- If an accident or contact occurs call 911 immediately (or your country’s emergency line if in another country). Never touch a person that is in contact with a power line (you’ll also be electrocuted).
- Instruct and ensure everyone involved in the installation understands the safety and power line warnings.
- Never remove anything that has made contact with a power line, as it can be lethal or can cause electrocution during the removal process! Contact your local utility company’s emergency line for assistance!
- In addition to antenna, keep mast, tower, mount, and all guy wires (if applicable) well away from power lines, as all of these act as electrical conductors of electricity.
- The distance between any power lines and the installation site should be at least two times the total height of the mast, tower, and antenna assembly plus the length of the antenna. Make the separation distance away from power lines even greater if possible.
- Since all overhead power lines look somewhat alike, consider them all dangerous and stay well away from them.
- Add the antenna to the mast first, prior to mast erection. If using guy wires, estimate the length of each wire first and make sure none can come near any power lines during erection, installation, or falling. Use the double rule, of all power lines should be at least double the mast height plus double the antenna length away.
- Install the guy ring on mast and connect guy wires with appropriate guying hardware and clamps.
- Note, the mast is highly unstable prior to finishing all guying; you must have someone also hold the mast upright while the guy wires are attached and tightened to stay anchors.
- "Tie off" the mast with dry, non-conductive ropes so you can control side sway and the direction of fall as you walk assembly up. If it does start to fall, let go of it and let it fall.
- Don't attempt to "walk up" a mast over 30 feet tall. Get a professional to do it for you.
- Once the antenna is up in full vertical position, securely fasten by using the instructions included with your chosen mount.
- Also add necessary lightning protection, by properly grounding your antenna and mast/tower (see grounding safety section for more about proper grounding methods).
EMERGENCY AID FOR SHOCK
- It is advisable to work with several other people when installing or removing an antenna. One person should stand aside to direct the effort and watch for signs of trouble. If someone does receive a shock, don't touch the victim while his body is still in contact with the electricity. Instead, pry or pull him away from the source of electricity with a length of dry wood, rope, a blanket, or another non-metallic object.
- If breathing has stopped, use mouth-to-mouth resuscitation until a doctor or ambulance arrives and relieves you. If the heart has stopped, closed-chest cardiac massage must be done simultaneously. The ambulance should be informed when called that an electric shock has occurred; it can bring proper equipment such as an intensive care or cardiac care mobile unit equipped with a heart defibrillator and carrying trained personnel.
ANTENNA GROUNDING & LIGHTNING SAFETY
- To protect your home and TV and inter-connected electronics, a properly grounded system is necessary.
- Grounding the system is something you can probably do yourself. But if you’re not sure, you should contact a qualified electrician.
- You can buy a grounding rod, grounding blocks, clamps, wire, and related grounding accessories at most local hardware stores.
- Use a #10 copper or #8 aluminum grounding wire or larger, properly fastened via a proper grounding clamp to the bottom of the mast. Using stand-offs every 4 to 6 feet, run the wire down the building in as straight a line as possible.
- The NEC requires that the antenna mast and mount be grounded directly. No splices or connections are allowed in the ground wire between the mast and the ground rod.
- Also add a lightning arrestor or a 75-ohm grounding block to the antenna’s lead-in cable as close as possible to the point where the cable enters the house.
- Attach the grounding wire to the lead-in cable’s grounding unit and run the wire to the central building ground, which is the home’s main ground rod, typically installed at the power meter and breaker box.
Alternative Grounding electrode methods must be acceptable NEC grounding methods such as:
- Grounded interior metal cold water pipe within five feet of the point where it enters the building.
- Grounded metallic service raceway.
- Grounded electrical service equipment enclosure.
- Eight-foot grounding rod driven into the ground (may be used only if bonded to the central building ground by #6 or heavier bonding wire). You can buy a grounding rod, grounding blocks, clamps, and wire at most local hardware stores.
- Other acceptable grounding electrodes that comply with sections 250 and 810 of the National Electrical Code (NEC)
- DO NOT assume that just because you're on a roof, you're isolated from ground. You may still be electrocuted or fall off the roof.
- Also obey power line and grounding warnings in this manual.
UN-INSTALLING THE ANTENNA:
Use these same safety guidelines for the removal or your antenna (but in reverse order).
