Notes:
1.  All Yagi antennas are assumed to use DL6WU stacking distances.  Therefore, the stacking game used is 2.9 dB.
2.	Many stations are using stacking distances considerably less than DL6WU.  As a consequence, actual stacking gain is often in the 2.6-2.8 dB range.
3.	The collinear antennas are considerably understacked in the H plane.  Therefore, the gain figures have been adjusted accordingly.
4.	No stacking harness losses are included in the gain figures.
5.	The program used to calculate the antenna gains etc was NEC for Yagis 2.0.  20 segments per element were used for good accuracy.
