Antennas-Amplifiers Product Benefits. A Major advance in Amateur Radio antenna design.

 

  • F/B and G/T superiority.
All antennas have been calculated using state of the art full 3D Electromagnetic Simulation Software including the influence of the boom, bracket, baluns and connectors. The performance of antennas designed using these techniques are exceptional, far better than antennas designed using “wire” programs.

 

  • No tuning antennas

Before dispatch, we assemble each antenna and test antenna characteristics. That means you may expect exceptionally good electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to move dipole, cut or tune any element to get perfect SWR on intended frequency range. Everything is pre tuned.

That lead also to another very important detail. When assemble and test each antenna is complete with all washers, nuts, bolts guy rope supports etc.
When packing all parts are already on antenna without possibilities to “forget” important parts to put in the box. So you will always receive complete antenna what we tested just before dispatching.

 

  • Designs that work well in all weather conditions
  • Low SWR and superior G/T, F/B and F/S ratios across the entire bands
  • Excellent mechanical properties
  • High durability, built without compromise

 

Why all above is very important? Why we do not use free wire programs like EZNEC (Pro), 4NEC2, MMANA-GAL or AO? Like all other producers or simulators do?

EZNEC, 4nec2 or AO producers or simulators puts on the web pages excellent “simulated” antenna patterns  produced by wire programs. Looks good on computer screen. But what about reality?

Elements are not infinitesimally thin.
Boom size is not 0 (zero) mm.
Boom corrections programs exists. But what about accuracy?
Electrical terminals from balun coaxial cable to dipole are probably at least 10 mm long what is not “simulated” 0 (zero) mm. It will lead to worsen SWR or when tuned to good SWR to sharp antenna resonance.
Real antennas are not in free space. They are surrounded by metal parts not calculated in any form by wire programs.

Errors made by amateurish programs like EZNEC (Pro), 4NEC2, MMANA-GAL, AO, etc. only for the above examples are unacceptable in these days. They will lead to wrong antenna gain and specially F/B. At least 5-15 dB lower than predicted. That mean if the antenna is “calculated” for F/B 30 dB it could be anywhere between 15dB to 25dB. Unfortunately that also mean antenna will have much worse G/T which will lead to bad contest results and poor EME reception. 

This has nothing to do with obtained SWR of 1: 1 on antenna. SWR 1:1 is not related in any circumstances with antenna gain, F/B or G/T.
