Abstract: We present images of the parsec-scale polarization structure in the nuclei of three lobe-dominated quasars from the Jodrell Bank 966 MHz survey: 0723+679 (3C179), 1150+497, and 1317+520. Studies of extended sources, whose jets cover a wide range of orientations, are important for testing physical models of polarized emission. The core in 0723+679 shows a rest-frame rotation measure of ∼1400 rad m−2. All three sources have low-polarization (< 2%) cores and moderately-polarized (often > 10%) jets, with evidence for strong polarization (≥20%) on the component edges. All three jets exhibit predominantly longitudinal magnetic fields, with no Faraday rotation. The cores have flatter spectra than the jets.
