What others say about PA50-6-6:
 
Erwin DK5EW
"The antenna was very well packed in a very hard cover so there was no damage due to transport.
Today I installed the antenna. The installation was very easy as you marked all parts perfect in that way that a mistake is impossible.
The quality of the antenna material is great also the mechanical workmanship is fine.
It took me about 1 hour to mount the antenna and another hour to install it on the tower.
The SWR is - as you promised  - very low in the ordered frequency range.
Please find attached a picture of the antenna and a SWR plot I made with my VNA

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 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).
