Comparisons of 40 Meter Multi Element Wire Antennas based on analysis using NEC
All antennas are 45-50 feet above ground, using Sommerfield-Norton Ground parameters of Conduct =5ms , Dielectric=13
These are 'nominal models" where we have not attempted to optimize parameters, we simply want a sense of practicality and performance.
3 Yagi's are shown as well for reference.
Antennas:
| 3 El Mini-Horse
~48' Wide ~28' F/B
|
 The current in the Director wire was ~ 30% of the DE and and 50% of the Reflector, so I deleted the Director and made a 2 El Mini Horse (next below) |

| 2 El Mini-Horse ~48' wide ~17' FB |
Well, this begins to look like a Moxon, so Moxon details below. |

| 2 El Moxon
51 x 17 |
 The Moxon is simple and has good performance. You loose 2db for sure, but it is a simpler antenna with Gain and F/B ratio. |

| 2 El Shorty 40 |
 Has 4 loading coils 20-22uh |
