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 and test every antenna. That means you may expect outstanding electrical and mechanical characteristics including low SWR across the complete frequency range.
Everything is pre-tuned.

 

• Easy to set up

23cm antennas come already assembled. No need to tune or touch any element.
Everything is included in the antenna box: Antenna, balun with connector, and bracket.
