  Spectral analyses of extreme horizontal branch (EHB) stars indicate a trend
to supersolar heavy-metal abundances that is increasing with effective
temperature. The sdOB EC11481-2303 is such a star, located at the very hot end
of the EHB. In contrast to other sdOB stars, it is exhibiting an extraordinary
flat UV continuum. This may be the result of extreme metal-line blanketing. We
present preliminary results of a spectral analysis by means of static as well
as stratified NLTE model atmospheres.
