Phased Array Element Count to Approximate Directivity
n		dipoles
1 dBd = 2.15 dBi
Ground plane adds 3 dBi
D =		dBd (LP)
D =		dBi (LP)
D =		dBi (LP w/ Ground plane)
D =		dBi (CP array + CP signal)
D =		dBic (CP array + CP signal)
LP = Linear polarization
CP = Cicular polarization
CP arrays require an even number of orthogonal dipole elements (minimum two elements)
