HT-20 LPF performance?

I am curious about the performance of the HT-20 LPF.  Has anyone measured harmonic suppression numbers?

Curt-

ARRL's December 2018 review showed 2nd-harmonic suppression as -50 dBc. That number will vary somewhat with component tolerances, but the Hilltopper meets FCC spurious emissions standards.
