We do not use “amateur” programs like NEC4, NEC2, 4NEC2, EZNEC, YO or AO.

We perform the design work using the latest professional full-3D electromagnetic modelling software. This enables us to accurately include the influence of the boom, insulators, baluns, feed point, connections, etc.

Our designs are optimised using the Particle Swarm algorithm, which is considered one of the best global optimization algorithms. We also use the classic Nelder-Mead Simplex algorithm for fine tuning. Our optimization runs frequently exceed 1 million evaluations. We rely on solid physics, not on “clever” tinkering with antenna elements or spacings.

Our antennas are precision physical instruments, they are real “Precision Antennas” (PA).
