Uum but if the moonbase is at the south pole then it wont even be line of site to the earth for >50% of the time.
Hence this idea of three satellites in elliptical lunar orbit

Or maybe it would be cheaper/simpler just to have a nice big telescopic tower to see over the horizon or even some lunar repeaters on nearby hilltops which have been delivered and placed by unmanned rovers which would help with base to mobile comms on the lunar surface and have moon<-> earth comms capability as well.
Sounds like they really need some ham "experts" to work on these issues:)

With the amount of libration on the moon, what's the maximum antenna gain per band that you can get before it becomes too much of an issue.

Perhaps this should be in the Amsat FAQ =%-)
