Jim,

Which 8 circle version are you referring to?? The HiZ-8 or the Broad Side-End Fire (BSEF) 8 vertical array?

The HiZ-8 uses all 8 verticals for each direction but the BSEF array only uses 4 verticals for each direction.

I'm looking at putting out an 8 circle but three of the antennas on the
circumference may need to be seasonally placed since they would be on my
neighbor's property.

If those three were removed would the remaining 2 elements for each
(opposite) direction left in place still produce a cardioid pattern if
switched toward those directions? I'd terminate the removed lines with 75
ohm terminations of course.

I would leave the center element and the remaining 5 elements on the
circumference in place year round to minimize seasonal work if needed.
