144 MHz Hi Gain Wideband Antennas
The "Dual" company has been producing antennas for more than 25 years.
Our focus is on: wide bandwidth, designs that work equally well in all weather conditions,
very low SWR and superior G/T, F/B and F/S ratios across the entire frequency band,
excellent mechanical properties, and uncompromised durability.
We perform the design work using the latest full-3D electromagnetic modelling software.
This enables us to accurately include the influence of the boom, insulators, baluns, feedpoint
connections, etc, to the level which is impossible to do with legacy software (NEC2, NEC4,
MiniNEC, EZNEC, 4NEC2, AO, AOP, YO).
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 Simplexalgorithm 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.
By paying the greatest attention to all of the important details, we are able to consistently
produce top performance designs.
Our antennas are precision physical instruments, they are real "Precision Antennas" (PA).
