Antenna gain is proportional to area (ignoring efficiency) so to get 40 times the gain you would need a little more than 6 times the diameter for a dish antenna. So, if you could receive AO-40 on 2.4GHz with a 1 meter dish, you would need something around a 6 meter diameter dish to receive AO-40 if it were on the moon.
But if, instead of SSB, you used a mode which was able to cope with a 16dB weaker signal (plenty of weak signal data modes to choose from), then the 1m dish would work.
