  Valley chiral kagom\'e networks can arise in various situations, like for
example, in double-aligned graphene-hexagonal boron nitride and periodically
strained graphene. Here, we construct a phenomenological scattering model based
on the symmetries of the network to investigate the energy spectrum and
magnetotransport in this system. Additionally, we consider the effects of a
finite Rashba spin-orbit coupling on the transport properties of the kagom\'e
network. We identify conditions where the interplay of the Rashba spin-orbit
coupling and the geometry of the lattice results in a reduction of the
periodicity of the magnetoconductance and characteristic sharp resonances.
Moreover, we find a finite spin-polarization of the conductance, which could be
exploited in spintronic devices.
