  Multi-frequency observations of Mrk 348 are presented consisting of 2 epochs
of MERLIN data at 5 GHz, ISOPHOT data at 170, 90, 60 and 25 micron, NOT images
at U, B, R and I bands and data at 1350 micron from the archive for SCUBA. The
new optical images reveal a disrupted arm that ends towards the eastern
companion of Mrk 348, consistent with the hypothesis that Mrk 348 and its
companion form an interacting system. 5 GHz MERLIN imaging shows that only one
of the radio components of Mrk 348 is polarized (%P=5). The broadband spectrum
of Mrk 348 is flat between the radio and millimetre bands, suggesting that
synchrotron emission extends to high frequencies. Mrk 348 has many of the
characteristics of a radio-loud object. We discuss the orientation of the radio
axis of Mrk 348 with respect to the line of sight. We conclude that the
evidence is conflicting, and the geometry in Mrk 348 is not well-described by a
simple edge-on or face-on model.
