  Radio holographic measurements using the MeerKAT telescope are presented for
each of its supported observing bands, namely UHF (544--1087 MHz), L (856--1711
MHz) and S (1750--3499 MHz). Because the UHF-band receiver design is a scaled
version of that of the L band, the electromagnetic performance in these two
bands are expectedly similar to one another. Despite also being linearly
polarized, S-band receivers have an entirely different design and distinct
performance characteristics from the lower two bands. As introduced in previous
work for the L band, evidence of higher-order waveguide mode activation also
appears in S-band measurements but there are differences in its manifestation.
Frequency-dependent pointing (beam squint), beam width, beam ellipticity,
errorbeam, instrumental polarization and cross-polarization power measurements
are illustrated for each of MeerKAT's observational bands in a side-by-side
style to facilitate the comparison of features. The derivation of collimation
errors and main reflector surface errors from measurements made at these
relatively low observation frequencies is also discussed. Results include
elevation and ambient temperature effects on collimation, as well as the
signatures of collimation degrading over time. The accompanying data release
includes a snapshot of full Jones matrix primary beam patterns for all bands
and antennas, with corresponding derived metrics.
