PLOT INFORMATION - all plots are shown at an installed height of 35' (~11m):

Horizontal antennas produce lobes related to frequency and height above ground.
    The number of lobes is equal to 2 X the height above ground in wavelengths.
         An antenna at a height of one (1) wavelength will have two (2) lobes.
            An antenna at a height of 1/2 wavelength will have one (1) lobe.
                An antenna at a height of 3/4 wavelength will have one (1) lobe, plus the beginning of another at a high angle.

     Wavelengths above ground for Q52 installed @ 35'
