[TowerTalk] Verticals on a Hill.....Moxon

[lstoskopf at cox.net]

 Moxon was/is my antenna god.  In his "HF Antennas For All Locations" by RSGB, p.140, Fig 10.15:

"Uselessness of vertical polarization for the exploitation of steep ground slopes.  Image is tilted back into the slope so that it is normal to the direction of propagation and therefore wasted.  It is in any case attenuated due to the reflection coefficient being less than unity.  Situation is even worse with antenna normal to the slope as shown dotted."

That may be the reason no one seems to have developed a computer program for modeling verticals over slopes.  Not worthwhile.  Or maybe difficult.
I always regret that when I attended the RSGB convention way back that Moxon was too ill to attend.  One of many leaders/thinkers in our hobby worth remembering.  My SteppIR at the edge of a hill models out on HFTA to work just as he described well before that program was written.
