6.2 Model 3142C Typical 26-3000 MHz Antenna Factor
Distance for the ANSI 3 and 10 meter calibrations is measured from the antenna
midpoint, and for SAE 1 meter calibrations the distance is measured from the
antenna tip. Midpoint is defined as half the distance between the small elements
and the bow-ties, which is about 45 cm from the small end tip.
