Antenna PA432-14-3B 14el 430Mhz

The Antennas-Amplifiers has been producing antennas for more than 30 years.

 Their 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.

They do not use amateurish programs like EZNEC Pro/4, 4NEC2, EZNEC, MMANA AO or YO They perform the design work using the latest professional full-3D electromagnetic modelling software. This enables them to accurately include the influence of the boom, insulators, baluns, feed point, connections, etc

Their designs are optimised using the Particle Swarm algorithm, which is considered one of the best global optimization algorithms. They also use the classic Nelder-Mead Simplex algorithm for fine-tuning. Their optimization runs frequently exceed 1 million evaluations.

They rely on solid physics, not on "clever" tinkering with antenna elements or spacings. By paying the greatest attention to all of the important details, they are able to consistently produce top performance designs.

Their antennas are precision physical instruments, they are real "Precision Antennas" (PA)
