This estimation differs from Einstein's Quadrupole Formula (EQF) by a suppression factor ($Π\ll1$). For a symmetric two-body-like distribution of scalar matter $Π$ is estimated to be $\ll(v/c)^2(r/R)^2$, where $v$ is orbital velocity of the bodies, $c$ - velocity of light, $r$ - radius of each body, and $R$ -- the inter-body distance. This contradiction with EQF is briefly discussed.4 pages, 1 figuresGeneral Relativity and Quantum Cosmologytext
