1.25m 222MHz CROSS DX EME Antenna 222CROSS30DX

Super low noise, extreme gain 1.25m 222MHz CROSS DX EME Antenna 222CROSS30DX for ITU Region 2. The highest possible suppression of all side lobes and the best G/T was achieved with about 15 days of optimization. Devoted for low noise EME and DX hunting. With this antenna, you will hear extremely weak signals via the Moon with the ability to change polarization. Maximum polarization mismatch is -3dB with just one single H/V relay.

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.
Comparison of EM simulation software

  • 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 tune the dipole, or any other 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.
Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is to assemble and have fun!

  • Mechanical properties

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