  We show that $\Theta$-positive Anosov representations
$\rho:\Gamma\to\mathsf{PO}(p,q)$ of a surface group $\Gamma$ satisfy root vs
weight collar lemmas for all the Anosov roots, and are positively ratioed with
respect to all such roots. From this we deduce that $\Theta$-positive Anosov
representations $\rho:\Gamma\to\mathsf{PO}(p,q)$ form connected components of
character varieties.
