A dipole over ground
wrote in message ... Wayne wrote: wrote in message ... The following shows the effect on elevation pattern for a 1/2 wave dipole antenna over ground at various heights for perfect, very good, average, and extremely ground. The important value to note is the elevation angle for the main lobe. snip Perfect V good Avg Ext poor Height gain @ elev gain @ elev gain @ elev gain @ elev 0.10 8.6 90 6.3 90 4.4 90 3.1 90 0.15 8.4 90 7.1 90 5.8 90 4.3 90 I'm having trouble wading through the data, probably because of column headings. Let's take the first line. 0.10 Would be the height I get lost after that. Is 8.6 the gain over perfect ground, 6.3 over good, etc. What are the 90's? Wayne W5GIE/6 # Height is the height in wavelengths. # gain is the gain of the main lobe. # @ elev is the elevation angle of the main lobe; 90 means straight up. # And there are three sets for perfect, very good, average, and extremely # poor ground. # It all lines up in ASCII; if the spacing is screwed up, you are likely # viewing it as HTML. Not using HTML, but your explanation clears it up. Thanks. |
