*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'*	.5	*.64*	*.76*	*.88*	1
*Number of lobes the antenna should have @ 35'*	1	*1 1/4*	*1 1/2*	*1 3/4*	2
