  • Wireless transmission or reception signals for mobile communication are generally restricted to a travel distance.
  • a base transceiver station (BTS) or a repeater is installed at a predetermined interval of distance or area according to terrain, and thereby a communication coverage range is widened.
  • antennas for the BTS are installed to be relatively higher than peripheral terrain features and buildings in order to avoid propagation failure of signals. Such installment forces the antennas to be exposed to lightning.
