A radio base station having a cabinet and a fan. The cabinet houses wireless communication equipment, and the fan cools the wireless communication equipment. The radio base station also includes at least one vent substantially perpendicular to air flow through the fan. This substantially perpendicularly arranged vent reduces atmospheric/ocean breezes from entering the radio base station and overheating the wireless communication equipment. The radio base station may also include at least one louvered vent having an open position and a closed position, the open position flowing air to or from the fan, and the closed position reducing the flow of air to or from the fan. The wireless communication equipment transmits frequencies between 806-960 MHz, between 1710-1885 MHz, or between 2500-2690 MHz.
