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 is 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 excellent electrical and mechanical characteristics including low SWR across the designed range immediately after assembling.
No need to move the dipole, cut, or tune any element to get perfect SWR on the intended frequency range. Everything is pre-tuned.


  • Easy to set up

Everything is labeled, just put number to number. The antenna can be assembled with hand tools in a couple of minutes.
Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is to assemble and have fun!

The old name of the antenna was PA432-14-3BV.
