4 FAQs about The impact of the rooftop opposite the communication base station EMS

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.

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.”

What if a rooftop antenna is too high?

Such levels might become an issue for maintenance or other personnel working on the rooftop. Exposures exceeding the guidelines levels, however, are only likely to be encountered very close to, and directly in front of, the antennas. In such cases, precautions such as time limits can avoid exposure in excess of the guidelines.

How much power does a rooftop antenna use?

The higher the power level, the greater the potential for exceeding established safe limits for exposure. They range from one to five megawatts of effective radiated power. These are the strongest sources of RF energy found on rooftops and particular caution should be used if required to access regions near the actual antennas.

Base stations and networks

The intensity of the radio waves is drastically reduced as the distance increases from the base station antenna. On the ground, in houses, and other places where people reside, the exposure levels from
