A system ( 10 ) for attaching a mast ( 11 ) of an antenna to a support post ( 12 ) includes a base plate ( 13 ) connected to the post ( 12 ), and a bracket plate ( 14 ) carrying the mast ( 11 ) and tiltably mounted to the base plate ( 13 ) by a plurality of connecting components ( 21 ). Each connecting component includes a bolt ( 37 ), two of which are received through notches ( 18 ) formed in the plate ( 13 ) and one of which is received in each track ( 22, 23 ) formed in the plate ( 13 ). A nut ( 42 ) tightens each of the bolts ( 37 ) to attach the plate ( 14 ) to the plate ( 13 ). When the bolts ( 37 ) are loosened, the plate ( 14 ) may be lifted relative to the plate ( 13 ) to move the bolts ( 37 ) out to the notches ( 18 ). Thereafter, the plate ( 14 ) may be tilted relative to the plate ( 13 ) to pivot a bolt ( 37 ) in one of the tracks ( 23 ) about a bolt ( 37 ) positioned in a pivot point ( 27 ) of the other track ( 22 ) to lower the antenna to the ground where it may be conveniently serviced.
