Many people do not realize the danger of installing a TV antenna. Although it may not top any "Top 5" lists of most dangerous ways to get injured or killed, the truth is that accidents during the antenna mounting process have occurred and thus safety should always be practiced even when it seems mundane and obvious.
Before starting, make sure that you have appropriate clothing for the job. Use a long-sleeved shirt and pants to avoid nicks, scrapes and cuts as you traverse up and down the ladder, and make sure that you wear shoes with rubber and good traction.
Don't ever work on a day when the weather is less than favorable. If rain looks like it's on its way, do not attempt to mount the antenna and think that you will beat the rain by hurrying up. Not only can mounting take longer than you anticipated but hurrying will leave more room for error.
Choosing an installation site is fairly easy as long as you keep one important rule: keep it away from power lines. Do not assume that the line that is running close to your house is a phone line; always assume that it is a power line because you can never side with caution enough with this one. Choose a place where the antenna cannot fall on or touch the power lines.
If you have chosen to install your antenna on a tall mast rather than directly on you roof, make sure that the total length of the mast plus the antenna is double the length of distance from the antenna site to the nearest power line.
Because there is the risk of electrocution during the mounting process, it is recommended that you work with someone just in case an emergency occurs. If electrocution should occur, make sure that the both of you are aware not to touch the other while electrocuted. Touching the person will only result in two electrocuted persons. Try to separate the person from the source of the electricity by using a dry stick, rope, or other non-conducive object. Afterward, seek medical assistance immediately even if the electrocuted person seems and says that he or she is okay.
If the antenna itself or other part comes into contact with a power line, don't attempt to remove it yourself. Instead, call your power company immediately, and they will send a technician over promptly to remove it safely.
