What does 2m22CROSSDX mean?

  • 2m 2m band
  • 22 – 22 elements, 11 elements of horizontal polarization, and 11 elements of vertical polarization
  • CROSS – CROSS Yagi antenna has horizontal and vertical elements – separated on a single boom, the antenna is mounted in a “+” format.
  • DX – For use in the DX part of the band 144-145MHz.

What about Orthogonality and related to that isolation between antennas (coupling) say SM5BSZ

“The NEC simulations above show that an isolation of 20 dB is sufficient. This means that the obvious way of checking a cross Yagi is to connect one of the feed lines to a transmitter with known output, and a power meter and a dummy load to the other. The attenuation is then measured directly through the power arriving at the dummy load. If it is below -20 dB compared to the transmitted power everything is fine. ”

Excellent results of isolation achieved -30 dB. Much better than SM5BSZ suggested:

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!

The old name of the antenna was PA144-CROSS-22-7AGP
