¡La installation de este producto cerca de líneas eléctricas es PELIGROSA! Para su seguridad, lea todas las advertencias en este manual antes de la instalación.


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 proper installation and grounding safety techniques as defined by the NEC are recommended. 



  • Assemble your new antenna on the ground at the installation site. Follow the assembly instructions that have come with it.
  • Ensure power line warner 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).
  • Install the selected mount for your antenna.
  • Add to 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 the side sway and the direction of fall as you walk the 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.
  • Ground the antenna according to the National Electrical Code (NEC) guidelines.

  • 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. Acceptable central building ground points.
  • You can buy a grounding rod, grounding blocks, clamps, wire, and related grounding accessories at most local hardware stores.
  1. 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.
  2. 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.
  3. 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:

  • 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)




  • Select a safe site to install the antenna.
  • The distance between any power lines and the installation site should be at least one and one-half times the height of the antenna and mast assembly. Make the distance 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.



  • NEVER work alone; always have someone near who can summon help.
  • Certain clothing may provide a degree of safety, but don't depend on it for your life (rubber boots or shoes, industrial rubber gloves and a long sleeve shirt or jacket).
  • 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 you need to use a ladder, make sure it is made of non-conductive (non-metallic) material. (This is a safety rule that you should follow whenever you're working with electrical equipment.)
  • 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 a power line!
  • Watch out for power lines. If the antenna, mast, tower, or other mounting solution comes near a power line, it can kill!  It’s not worth it, to put your life in danger!  Follow the warnings listed in this manual! 
  • WARNING: Power lines can kill! A safe distance away from power lines should be at least “double” the mast height plus double the length of the antenna!!
  • 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 power lines and/or loss of control of antenna, mast, and/or tower due to the wind forces applied on a large surface area.
  • With two people or more, assemble antenna on the ground and use help for the mounting of antenna, tower, and/or mast.
  • 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 of antenna, mast, or tower on 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.
  • Also add necessary lightning protection, by properly grounding (see grounding suggestions below):



  • 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.



  • 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.




Use these same steps and safety guidelines for the removal or your antenna (but in reverse order).
