70cm 42 elements EME World’s Best CROSS Yagi Antenna 70cm42CROSS

Exemplary good 42 elements EME World’s Best CROSS Yagi Antenna 70cm42CROSS with low noise characteristics and high suppression of all side lobes. Devoted for low noise EME and DX hunting. With these antennas, 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.

 

What does 70cm42CROSS mean?

70cm – 70cm band – 432-434 MHz
42 – 42 Elements – 21 elements for horizontal polarization and 21 elements for vertical polarization
CROSS – The Yagi antenna has both horizontal and vertical elements – separated on a single boom, the antenna is mounted in a “+” format.
Horizontal polarization – conventional mount horizontally polarized elements are parallel to Earth
Vertical polarization – as above but elements are perpendicular to Earth.

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 excellent electrical and mechanical attributes 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 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!

  1. Ian W6TCP

    I installed four CROSS antennas yesterday.
    I am very pleased with the design and build quality. I think they will last me a very long time.
    Thank you again.

    Regards
