  We perform a consistent modeling of cosmic ray electrons, positrons and of
the radio emission of the Galaxy. For the time we reproduce all relevant data
sets between 1 GeV and 1 TeV including the recent AMS-02 positron fraction
results.
  We show that below few GeV cosmic ray and radio data require that electron
primary spectrum to be drastically suppressed and the propagated spectrum be
dominated by secondary particles. Above 10 GeV an electron + positron
extra-component with a hard spectrum is required. The positron spectrum
measured below few GeV is consistently reproduced only within low
reacceleration models. We also constrain the scale-height of the cosmic-ray
distribution showing that a thin halo ($z_t \lsim 2 \kpc$) is excluded.
