Dipole aperture is the capture area which translates an incident field, in
W/m^2, to the actual power received by the dipole. For example the aperture
for a half wave dipole is 0.13(Lambda)^2, where Lambda is the wavelength in
meters. A 40 m half wave dipole would therefore have an aperture of 52
m^2. A horn aperture, and also a parabolic dish, aperture is the physical
area of the mouth of the horn.

Well, I sure read _that_ wrong! Thanks for clearing that up.
