  We report broad-band (1.2 - 1.9 GHz) radio continuum observations at
arcminute resolutions of two nearby disk galaxies, NGC 1808 and NGC 1097, and
four AGN powered radio sources; PKS B1934-638, PKS B0407-658, J0240-231, and
J0538-440. We use Rotation Measure Synthesis to analyze their Faraday
complexity. Observations were made with the KAT\,7 radio telescope array, in
South Africa. The AGN powered sources fall into two "Faraday" categories --
simple and complex. The most polarized sources, J0538-440 and J0240-231, are
found to have complex Faraday spectra that can be time variable (J0538-440
case) and also indicative of complex Faraday emitting and rotating components
along the line of sight. PKS B0407-658 shows a simple Faraday spectrum while
PKS B1934-638 is undetected in polarization. The disk galaxies are classified
as complex, albeit at low signal-to-noise. This may indicate depolarization due
to turbulence of the magnetised plasma in the bar and circumnuclear regions
and/or frequency-dependent depolarization at L-band
