   Effective Radiated Power (e.r.p.) (in a given direction). The product of the
   power supplied to the antenna and its gain relative to a half-wave dipole in
   a given direction.

   Equivalent Isotropically Radiated Power (e.i.r.p.). The product of the power
   supplied to the antenna and the antenna gain in a given direction relative
   to an isotropic antenna.
