ARRL EME Contest winner 70cm Low Noise DX Antenna 70cm23DX6A

Victorious DX and EME antenna in ARRL EME Contest 2021. Super low noise characteristics, unbeatable G/T, and maximum gain are key features of 70cm Low Noise DX Antenna 70cm23DX6A.

If you want to win the ARRL EME or UHF DX Contest, you will need a superior antenna not calculated with EZNEC with false performance and false G/T but an antenna with the real and best possible gain and G/T (+8.22 dB)  like this 70cm23DX6A calculated with state-of-the-art full 3D EM Simulation Software. 

Four of these antennas were used by PA5Y when he won the ARRL EME Contest in 2021Certificate.

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!
