This is an impact analysis on my antenna system using EZNEC. I did this studio to understand if and how there were relationship among the different antennas on my antenna site. I prepared a EZ file (towerFull)  which describes mysite (figure 1) and I modified it to obtain the different plots.

The modelling is based on plot comparison of the single antenna:

a)     with all the other “parasitic” antennas 

b)     without the other “parasitic” antennas

and to make the comparison, overlaying the plots.

Another analysis verifies the relationship between  the 7 mhz and the 15 mhz and between the 14 mhz and the 28 mhz antennas. See Download section .
