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.

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.

You might consider the 9 circle which uses 3 verticals for each
direction.? It might be interesting to model that with missing elements
in those directions but the other directions should work just fine.
The 8 circle uses 2 pair of phased elements.? It is hard to speculate
not know which elements would be missing.? It would seem to reason the
the intact pairs would work fine.
Most 8 circles do not have a center element.? That would be a 9.

I was doing the YCCC version which uses 9 antennas to form a 3 element
endfire in each direction.
I'm obviously limited in space here...
Thanks and sorry for the confusion

The 9 circle (3 element endfire) uses approximately 1:2:1 element
"drive". Removing one of the end elements will not yield a "clean"
pattern but you would need to model both 0:2:1 and 1:2:0 arrays to
see if the remnant pattern would be acceptable.

Nick I really don't understand what point you are trying to make . . .
Why do you think running High Power in a Contest is "harmful"?
Sure, you had more QSOs in the CQ160 this year (running Low Power) . . . but
you would expect that, as you were operating for 7 more hours compared to
last year !
I agree that you don't need to run High Power to work around Europe . . .
but if you want to work DX (such as W/VE) you really need to run high power
in a Contest or most stations over there simply won't hear you ! (as
demonstrated by the very few NA stations you worked)

I probably don't know how to tell sad jokes.. :-))))
I didn't work LoW in any of the contests.
I think that for participants from Eastern European countries, only two
categories should be left (SINGLE HIGH and MULTI HIGH).
UW0K is not my callsign ..............

Roger
another example of a "super" LOW performed by a fighter from the valiant
US1Q brigade:
Raw 2021 CQ WW CW Contest
CW / UT2IV / Assisted Low 160 Meters
1 UT2IV..............74,820
And here's what the real HIGH looks like..... :
CW / UY0ZG / Assisted High 160 Meters
2 UY0ZG..............70,799
3 UX0KR..............69,012

Ah OK . . . apologies Nick, I didn't realise you were being sarcastic !
Plus I presumed that the other station's Callsign was a special Contest
Callsign that YOU were using.
