[TowerTalk] New N6LF Ground Probe Designs

[gwj at me.com]

The one publication I know of that included information on sloping terrain is what N6BT wrote in NCJ. The graph at the end of the article came from a HOBBIES simulation by KI6OK, showing that a vertical adjacent to sloping ground will have the takeoff angle lowered a bit over 1 degrees for each degree of slope. Tom also discusses pattern testing with drones on his shallow-slope property.

>> N6BT has done work to show that the field strength and vertical pattern of vertical antennas is strongly dependent on ground slope.
