ABSTRACT
The nearby FRI radio source 3C 66B has been studied with the VLA at 1.5,8
and 15 GHz with high resolution and sensitivity. The first detailed maps
of the counterjet are presented. Polarization maps in the jet and
counterjet are shown; in each a resolved parallel-field region surrounds
a central core which changes from a parallel to a perpendicular field
configuration. A model of the jets involving a relativistic central
region and a slower outer sheath is discussed, and in this context 3C 66B
is compared with similar sources.

Key words: galaxies: individual: 3C 66B - galaxies: jets - radio
continuum: galaxies.
