I have this configuration. So does W7FU and the antennas at my place can
be seen on qrz.com. Height of 5BA is 100 ft. The 230/240 is at 115 ft.
The recommended spacing distance from Force12.

This combination (a Force 12 230/240 and a 5BA) appeals to me, too.
What can anyone tell us about how properly to stack them? In
particular, how far apart should they be on a single mast above a
70-ft. tower? (I assume that the 230/240 should be above the 5BA.)
