  An almost radial gauge $A^\mathrm{ar}$ of the electromagnetic potential is
constructed for which $x\cdot A^\mathrm{ar}(x)$ vanishes arbitrarily fast in
timelike directions. This potential is in the class introduced by Dirac with
the purpose of forming gauge-invariant quantities in quantum electrodynamics.
In quantum case the construction of smeared operators $A^\mathrm{ar}(K)$ is
enabled by a natural extension of the free electromagnetic field algebra
introduced earlier (represented in a Hilbert space). The space of possible
smearing functions $K$ includes vector fields with the asymptotic spacetime
behavior typical for scattered currents (the conservation condition in the
whole spacetime need not be assumed). This construction is motivated by a
possible application to the infrared problem in QED.
