70cm Low Noise Light EME DX Antenna 70cm17DXP 432-434MHz

70cm Low Noise Light EME DX Antenna 70cm17DXP with super low side lobes and excellent G/T. Lightweight of just 3.1kg, super gain, and F/B of 40dB are the key features of this antenna. It is equally effective for UHF contests and EME (Earth-Moon-Earth) operations, especially when using a system of four antennas.

A matching “H” Frame can be ordered upon request in three possible variants according to the proposed stacking distances.

This is not calculated with EZNEC, which yields false performance and G/T, but with the best possible gain and G/T calculated using advanced full 3D EM simulation software.

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, significantly outperforming those designed with the EZNEC program.
• No tuning antennas.
  Before dispatch, we assemble and test each antenna’s characteristics. No need to tune any element to get a perfect SWR on the intended frequency range. Everything is pre-tuned.
• Easy to set up.
  Everything is labeled, just put a number to a 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.
