From: Jim Jones <k0hy@comcast.net> CC: towertalk@contesting.com Pat What effect does a tall tower (100+) have on these angles? Seems to me a small change in elevation on 1 end would make a big change in angle a few miles away. 73 Jim Jim, the 100 ft tower changes the total elevation difference (Rise) of 1410 ft by 100 ft. over a distance of say, 12,000 ft.(Run) Using Tangent function, the 100 ft difference only changes angle by about 1/2 degree... (tan = rise over run) 73, de Pat AA6EG aa6eg@hotmail.com _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and lot's more.
