A lightweight rail that is bolted to the existing structure using standoff brackets. A carrier is attached to the rail to support the antenna. Once the rail and carrier are installed, access to an antenna is from the base of the rail. The rail is made of square aluminum tubing and the carrier is made of aluminum plate. In the lowered position, the carrier is readily accessible and the antenna mast can be tipped down to a horizontal position to access the antenna. The carrier and antenna are lifted using a hand winch, although a motor can be used as well. A simple cable system is used to hoist the carrier into the operable position at the top of the rail. Overall, the system is lightweight, low cost and safe to use.
