H166-alpha recombination-line (1424.734 MHz) observations are reported which were made at 13 positions in the Cassiopeia OB VI association. The H II regions IC 1795 (W3), IC 1805 (W4), and IC 1848 (W5) - which form a giant H II complex within that association - are investigated on the basis of these observations. The continuum brightness temperatures for the positions observed are given, and the results of continuum scans are presented as a contour map of antenna temperatures. A mean electron temperature of about 6900 K is obtained for the extended low-brightness regions of the complex. It is suggested that the 'diffuse' H166-alpha emission from the inner regions of the Galaxy may originate in regions similar to the Cassiopeia OB VI association, situated between 4 and 7 kpc from the galactic center, rather than in cool partially ionized gas.
