The present invention discloses a system for protecting a base station antenna that includes an antenna mounted to a platform base. The platform base can be raised and lowered depending upon an amount of pressure in a pressure chamber. A pressure generator can increase the amount of pressure in the pressure chamber. A depressurization valve can decrease the amount of pressure in the pressure chamber. A protective housing can protect the antenna from environmental conditions. When in a deactivated state, the antenna can be lowered into the protective housing. When in an operational state, at least a portion of the antenna can be raised above the protective housing so that the antenna can send and receive radio frequency signals.
