We used the Karl G. Jansky Very Large Array (VLA) at 3 and 6GHz to observe three Frontier Fields: MACS J0416.1-2403 (z=0.396), MACS J0717.5+3745 (z=0.545), and MACS J1149.5+2223 (z=0.543). The images reach noise levels of ~1{mu}Jy/beam with subarcsecond resolution (~2.5kpc at z=3), providing a high-resolution view of high-z star-forming galaxies that is unbiased by dust obscuration. We generate dual-frequency continuum images at two different resolutions per band, per cluster, and derive catalogs totaling 1966 compact radio sources. Components within the areas of Hubble Space Telescope and Subaru observations are cross-matched, providing host galaxy identifications for 1296 of them. We detect 13 moderately lensed (2.1<{mu}<6.5) sources, one of which has a demagnified peak brightness of 0.9{mu}Jy/beam, making it a candidate for the faintest radio source ever detected. There are 66 radio sources exhibiting complex morphologies, and 58 of these have host galaxy identifications. We reveal that MACS J1149.5+2223 is not a cluster with a double relic, as the western candidate relic is resolved as a double-lobed radio galaxy associated with a foreground elliptical at z=0.24.2021ApJ...910..105Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/910/105CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/380/199 : SCUBA Half-Degree Extragalactic Survey.
