Synopsis

Excerpt from Discussion of Errors in Gain Measurements of Standard Electromagnetic Horns

In order to increase one's confidence in the gain of the standard antenna, it is usually measured by a direct method. One well - known method [ieee Standard, no. 149, 1965] employs two identical antennas, one used to transmit and the other used to receive. The gain is determined from the ratio of transmitted to received power, the aperture separation, and the wavelength.

If such a gain measurement is to be useful in increasing confidence in the calated gain, the uncertainty in the measurement must lie within the limits h 0. 3 decibel. Although it is diffit to yze the errors and be certain of the limits of uncertainty, this is necessary if accurate results are required.
