Modeling a J-Fed 5-Element Collinear Antenna for the 2 m Band
If you’re looking for a high-performing omnidirectional antenna, consider this design. It boasts 5 collinear radiant elements that are connected by phasing coils. The feed point is conveniently located at the base of the antenna on a J dipole. By adjusting the position of the feed point along the J, you can minimize the SWR.

AN-SOF 8: Elevating Antenna Simulation to the Next Level
New Plots tab where we can quickly see the input impedance, VSWR, gain, Front-to-Rear, and Front-to-Back ratios as a function of frequency, with various visualization controls (grids, points, markers, etc.). The different parts of tapered wires are identified with alternating colors to better distinguish the wires of which they are composed…
Modeling a Multiband Dipole
Simulation of a multiband dipole for 3.7, 7.05, 14.2, 18.1, 21.2, and 28.5 MHz. There are 6 dipoles of almost half a wavelength each. They are all connected to the same feed point.
A Cardioid Small Loop
The so-called “Loop on Ground (LoG)” is a small loop antenna with a cardioid-shaped radiation pattern in the horizontal plane, used for reception.
Log-Periodic Christmas Tree
At Golden Engineering we are passionate about antenna simulation. On this last day of the year we want to give you our Log-Periodic Christmas Tree made with AN-SOF.
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…
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.
QFH Antenna for NOAA Satellite Reception
This Quadrifilar Helix (QFH) antenna, also known as QHA, can be used for signal reception from NOAA satellites. These are omnidirectional antennas made up of 4 wires with a helical shape.
