John,

At the bottom of the Wellbrook ALA-1530 information page, there is a
calibration chart which show the Aantenna factor vs frequency. It
indicates that the antenna factor is roughly 8 over most of the range.

How did you come up with a .45 factor?

The actual antenna factor is about -7dB, ie ca. 0.45, ie the antenna

output is ca. 0.45 volts for a field strength of 1 volt per meter. The
required antenna gain is then +33 - 7 = 26dB.
