What say DL8JJ about the antenna on his extremely successful EME expedition to Cameroon TJ9MD

Thank you for producing the best DXPedition single Yagi long boom antenna.
I used 2mCROSS30DXL on my EME DXPedition to Cameroon TJ9MD with great success!
You made a huge product and I’m pleased about that.
I did in all hard situations from there 138 QSOs.

What will happen if you try to calculate a “good” antenna with a free-of-charge EZNEC or with a small fee-paid version of EZNEC Pro/4 without the ability to calculate boom corrections or other surrounding metal objects? Read this.

 

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.
