A SAMPLE OF 6C RADIO-SOURCES DESIGNED TO FIND OBJECTS AT REDSHIFT Z-GREATER-THAN-4 - I - THE RADIO DATA

We describe the selection of a sample of 34 radio sources from the 6C survey from a region of sky covering 0.133 sr, The selection criteria for this sample, hereafter called 6C, were chosen to optimize the cha nces of finding radio galaxies at redshift z > 4. Optical follow-up ob servations have already led to the discovery of the most distant known radio galaxy at z = 4.41. We present VLA radio maps and derive radio spectra for all the 6C objects.
