Abstract: We prove a weak type estimate for operators of the form $ f \to \sum_{s\in\mathbf S}\langle f,\varphi s \rangle \varphi s $ for certain collections of Schwartz functions $\{ \varphi s \}_{s\in\mathbf S}$. This extends some of the orthogonality issues involved in the study of the bilinear Hilbert transform by Lacey and Thiele.
