We present a detailed statistical analysis of the alignment of polarizations
of radio sources at high redshift.
We use the JVAS/CLASS 8.4-GHz surveys for our study. This study is motivated
by the puzzling signal of alignment of polarizations from distant quasars at
optical frequencies. We explore several different cuts on the polarization flux
for our analysis. We find that the entire data shows a very significant signal
of alignment on very large distance scales of order 500 Mpc. The alignment
starts to decay only at much larger distances of order Gpc. If we only consider
data with polarization flux greater than 1 mJy, we find alignment at distance
scales less than 150 Mpc.
