Note: For such long antennas stacked, the propper segmentation number is too big, making calculation impossible in EZNEC with a common dual-core computer. Therefore I use a lower number of segments. The result shuld be very close to what has to be the true value. Just, the antenna gain (maybe for 0.05 to 0.1 dB), and the temperature (for 1.0 to 1.5K) are  a bit higher. Therefore, the G/T factor should be correct.
