Connection of two T-section posts between two half rings within an annular housing, whereby the T-section posts extend substantially parallel to each other and to the central axis of the bore of the annular housing. The annular housing may have a slightly tapered bore, whereby pressing the half rings into the bore of the annular housing presses the half rings tighter against the T-section posts, locking the T-section posts and half rings within the annular housing. The T-section posts may be rigid fiberglass-reinforced plastic. The annular housing may be a polyvinyl chloride slip coupling and the half rings may be cut sections of polyvinyl chloride pipe. The connection as described may be assembled by hand. A support structure for a UHF television receiving antenna uses two equal-length T-section posts connected between two half rings within an annular housing at each end of the posts; active antenna elements are attached to one T-section post and reflector elements are attached to the other.
