An apparatus for inline base termination of a monopole structure includes an upper base plate configured to be joined to a bottom end of a monopole, a lower base plate including a plurality of bolt holes, and a plurality of web plates connecting the upper and lower base plates, such that a virtual projection of the monopole through the lower base plate intersects the plurality of bolt holes. Another inline base termination apparatus includes a hollow monopole with outer shell, a base plate having a plurality of bolt holes formed therein in a circular pattern and evenly circumferentially spaced, and a plurality of web plates, each of which has a longitudinal slot configured to receive the monopole and is joined to the base plate between two adjacent bolt holes, such that a virtual projection of the hollow monopole through the base plate intersects the plurality of bolt holes.
