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

• F/B and G/T superiority.

All antennas have been calculated using state-of-the-art full 3D EM modeling 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 the EZNEC program.

• No tuning antennas.

Before dispatch, we assemble and test each antenna’s characteristics. No need to 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. Everything is included in the box: Antenna, balun, bracket, and guy rope support if needed. Yours is to assemble and have fun!

• Mechanical properties.

We believe that our antennas are the world’s strongest antennas and are mechanically constructed much better than any antennas from other manufacturers.
