Radio sources with declination above +60°, total flux density greater than 100mJy at 1.4GHz and angular size larger than 4' have been selected and observed with the VLA at 1.4 and 4.9GHz. The radio observations attempt to confirm the large angular size sources and to isolate the core emission for optical identification. In this paper, the first of a series of three, we present radio maps of 79 sources from the sample and discuss the effects of the selection criteria in the final sample. 37 radio galaxies belong to the class of giants, of which 22 are reported in this paper for the first time.
