Is this one of his single antenna models? I have his "Easy Satellite"
antenna, and used it to make 35 contacts on Field Day.
If it's a single antenna, like mine, you can rotate the boom in the
clamp so the elements are in an "X" position relative to the mast. This
puts each set of elements at 45* to the mast, very similar to the
suggested mounting when using two antennas on a metallic cross-boom.
That's how I mounted mine, and it works beautifully.

The stronger the better IMO. Although I realize there is a pretty minimal wind loan, and it will be mounted in a Glen Martin 4' roof tower, I'd rather not worry about my mast snapping in the wind...
