    New Release: AN-SOF 7.90

    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.

    Magnetic loop for 3.5, 7, 14, 21 and 29 MHz

    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.

    Go to AN-SOF main menu > Run > Run Bulk Simulation and select the five “.nec” files to run the calculations automatically. You can do it with the trial version of AN-SOF.
