Topband: Model of Single K8UR Sloper?

[Jeff Maass]

Has anyone modeled a single element K8UR sloper?

The K8UR sloper is essentially an inverted-V on it's side, 
with the feedpoint pulled out away from the tower. It is 
normally described as used in a 4-element switchable 
sloper array, as in the ARRL Antenna Compendium, 
Volume 4 in the article "The 160-Meter Sloper System 
at K3LR". 

The advantage of these elements is touted as reduced 
high-angle radiation and reduced horizontal component.
All the published patterns that I've seen are for the 4-element 
array, but I'm interested to see whether the same benefits
are there for the single K8UR sloper.

The applications is on 80m, with the goal being getting a little
more oooomph from Curacao to the USA, and I cannot use 
multiple elements in the space and circumstance we have
to work with on our 100-foot tower. 

Does anyone have the model to share?
