Do rooftop antennas cause RF emissions?When cellular and PCS antennas are mounted on rooftops, RF emissions could exceed higher than desirable guideline levels on the rooftop itself, even though rooftop antennas usually operate at lower power levels than free-standing power antennas. Such levels might become an issue for maintenance or other personnel working on the rooftop.
Are RF waves from cell phone towers safe?However, this does not mean that the RF waves from cell phone towers have been proven to be absolutely safe. Most expert organizations agree that more research is needed to help clarify this, especially for any possible long-term effects. How do cell phone towers expose people to RF waves?.
Can a person be exposed to RF levels on a roof?It is very unlikely that a person could be exposed to RF levels in excess of these limits just by being near a cell phone tower. When a cellular antenna is mounted on a roof, it is possible that a person on the roof could be exposed to RF levels greater than those typically encountered on the ground.
What if a rooftop transmitting site exceeds FCC limits?FCC limits for human exposure are based on a safety factor of 10, so even if a rooftop transmitting site exceeds FCC limits, while this could represent a regulatory breech, it still may be safe for firefighters to operate (depending upon signal strength) and how long one is exposed. “Whip antennas.”.
How high should a cell phone base station be?Cell phone base stations can be free-standing towers or mounted on existing structures, such as trees, water tanks, or tall buildings. The antennas need to be high enough to adequately cover a certain area. Base stations are usually from 50 to 200 feet high.
Should firefighters be aware of roof-mounted transmission devices?Curtis S.D. Massey discusses the importance for all firefighters and chief officers to be aware of roof-mounted transmission devices and how they might affect their safety during any type of rooftop operation.
