  In this paper we present near-infrared K-band imaging of a sample of
ultra-steep spectrum (USS) radio sources selected at 74 MHz. The dual selection
criteria of low frequency and USS means that we should be sensitive to the
highest redshift (z > 5) radio galaxies. We have obtained $K-$band magnitudes
for all of the objects in our sample of 26 and discuss the properties of each.
  There is a pronounced bias in this sample towards fainter magnitudes and thus
higher redshifts when compared to complete unfiltered samples such as 7CRS
(Willott et al. 2002), implying that the steep-spectrum technique is still
viable at 74 MHz. However, there are more bright (K < 17) sources in the 74 MHz
sample than in a similar sample selected at 151 MHz, namely 6C*. This is
principally due to the additional selection criterion of a small angular size
for the radio sources in 6C*, four of the six sources in the 74 MHz USS sample
with K < 17 have angular sizes > 15 arcsec (the angular size cutoff of 6C*).
  We find that the distribution of K-band magnitudes from a sample selected at
74 MHz is statistically indistinguishable from the 6C* sample, when similar
angular size filtering is applied to the 74 MHz sample.
