Hi-VHF Vertical Folded Dipole OMNI
Hi-VHF Vertical Folded Dipole analyzed using 4nec2. It provides a TRUE OMNI-Directional
Azimuthal Pattern, but ONLY for Vertical and Circular/Elliptical Polarized signals.
Fol. analysis assumed fol. Dimensions:
L2=27.5 ' Folded Dipole Overall Element Length
FW=2.0 ' Distance between Folded Dipole Elements
RACT=0.2845 ' Radius (inches) for Driven Element is Standard Type M 1/2-in O.D. Copper Tubing
Dimensions for other Diameter Tubing and it's effect on SWR can be found in the analysis for
Hi-VHF Folded Dipole for Horizontal Polarized signals, as well as a DIY Construction Example:

Note that it's the SAME Antenna, except oriented Vertical or Horizontally. |
