This version of AN-SOF has new functions and options:
- ARRL-style scale in polar plots. Radiation pattern slices in decibels can be displayed on the classic ARRL log scale. This facilitates the comparison between the results obtained from AN-SOF and data published in magazines and in the antenna literature.
- Front-to-Rear (worst-case) and Front-to-Back (180-degree) ratios are indicated on polar plots.
- Export radiation patterns in MSI Planet format. See how here >.
- Improved Preferences window in the AN-XY Chart app, where we can set scales, units, line thickness, points, marks, and grids on rectangular charts.
- Visualization of the wire segments in the workspace. Check the “Show Segments” option in the Preferences window to see the segments.
Tip: double click on table items to instantly display plots.
This small transmitting loop antenna is 1 meter high above average ground, so the radiation pattern is not donut-shaped as expected for a small loop in free space. The value of the tuning capacitor is indicated for each resonance frequency.
Large loop: 70 cm in diameter, RG-8 cable.
Small loop: 15 cm in diameter, RG-6 cable. Inductive coupling between the feedline and the large loop, spacing of 2 cm.
The color scale on the loops indicates the current flowing for a reference voltage of 1 V.
