[HCDX] Index of curtan array directivity arrangements HRS12/4/1 to HRS2/2/1

Index of curtan array directivity arrangements HRS12/4/1 to HRS2/2/1

Most to least ...

HRS 12/12/1 (only theoretically, never built)
HRS 12/4/1 (VOA Delano)
HRS 8/8/1 (not commonly used: Russia, others?)
HRS 8/4/1 (Jordan, hopefully RCI Relay Stations in BC and Sask ... and a few
others)
HRS 6/4/1 (VOA Delano, Morocco #3 etc ...)
HRS 4/4/1 (common as dirt)
HRS 4/3/1 -- part of my RCI BC SW Relay Station proposal. Useful for its
nulls, but directive like a 4/4/1 antenna.
HRS 2/4/1 (directional in tropics)
HRS 2/2/1 (RNZI, other tropical users)

S : slewable Horazontally (-/+ 15 degrees max) or Vertically (000 to +++),
no HRSHV notation has ever evolved.

1 = 1.0 wavelengths above the ground for the lowest row of emitting dipoles,
very often 0.5 or 0.75 or 1.25 depending on emission frequency. Skywave
propagation is affected by this number, so it is important. I use 1 as a
defult, for simplification.
