Bear in mind that it also depends on the orientation of the rod relative to the incoming wave, and to the polarization of the wave. Modern stealth aircraft tend to reflect the signal away from the transmitting radar or absorb it. The windows tend to have thin conductive gold layers on them to stop radio waves getting into the cockpit and finding a resonator. Similarly joints on the fuselage are sealed. However, the design of stealth is limited to a frequency band, normally X-Band (8 to 12GHz, a few inches in wavelength). At a lower frequency, like 1GHz they are not stealthy, which was one reason why an F-117 Stealth fighter was shot down in the late 1990's.
