I prefer the bigger antenna (in this case the 40M) on the bottom just as
a practical consideration since larger antennas tend to need more maintenance
over time. Having it on the bottom just makes it easier to drop for repairs.

You mean total mast length or mast sticking out of the tower? It's
been my limited experience that you need at least 10 feet of spacing for an
XM240 and more would be better.
