How to increase a coverage zone?
A very big influence on a coverage zone makes transmitting antenna. Rise of the antenna above nearby houses can strongly increase a zone of service by 5 meters: it is equivalent to increase in capacity of the transmitter approximately in 10 times. The transmitter with 25 Wt amplifiers, at use of the antenna with factor of amplification 10 дБ is equal to the transmitter with radiation capacity 250 Wt.
By consideration of a problem of increase in a cover zone nevertheless it is necessary to remember, that the maximal capacity of the used equipment is limited to the factor of electromagnetic compatibility and similar questions should be solved together with CEMC.
