Due to the weight of the boom the elevation boom and reflector must be sup- ported during the elevation brake replacement process. The antenna elevation axis should be driven to an angle high enough to provide clearance to work under the boom on the brake assembly. A 2 X 4 inch piece of lumber (or equiv- alent) should be used to support the boom and reflector as detailed in Figure
9.The elevation axis should be driven down until the boom and reflector are resting on the 2 X 4.
