Comparing Four Wire Antennas and Introductions to their Generic 4NEC2 Models (008h)

In this video I am going to be do two things:
1. I will introduce you to the Generic Modeling files for the Dipole/Inverted-Vee and the Folded Dipole/Folded Inverted-Vee antennas
2. I will use these two generic models to simulate four common wire antennas and compare their performance on several metrics.

The four antennas I will be comparing are:
1. The Dipole
2. The Folded Dipole
3. The Inverted-Vee
4. The Folded Inverted-Vee

The metrics I will be looking at include:
* Feedpoint Impedance
* Bandwidth
* Best SWR
* Radiation Efficiency
* Gain
* "Take-Off" Angle
* Beamwidth

I have provided the original modeling files and the Excel spreadsheet in a ZIP file for you. You will find the link to this file below.
