Are there any safety concerns regarding antennas or the radio system in general?
A. Yes. Aside from the obvious concerns, such as safety when you climb structures or when you work with dangerous AC line voltage, you must also be aware of the issue of exposure to RF radiation. There is still a lot that is unknown, so there is much debate about the safe limits of human exposure to RF radiation. Remember that the use of the word “radiation” here does not necessarily connote any linkage to or issue with nuclear fission or other radioactive processes. The best general rule is to avoid unnecessary exposure to radiated RF energy. Do not stand in front of, or in close proximity to, any antenna that radiates a transmitted signal. Antennas that are only used to receive signals do not pose any danger or problem. For dish-type antennas, you can safely be near an operating transmit antenna if you are to the back or sides of the antenna, because these antennas are directional and potentially hazardous emission levels are only present at the front of the antenna.
