Re: Topband: " LOW POWER "
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 --- Nick, UY0ZG http://www.topband.in.ua uy0zg писал 2022-02-08 07:48: Roger I probably don't know how to tell sad jokes.. :- I didn't work LoW in any of the contests.

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. 73, ...

Re: Topband: 8 Circle question
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.

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