What does 2m70DX41-2Conn mean?

2m band – 144 – 145 MHz with low SWR on any frequency.
70cm
band – frequency range 432 to 434 MHz with low SWR
DX – Intended for use for DX hunting or catching super weak EME signals
41 13 elements on 2meter and 28 elements on 70cm band with excellent gain. Comparable with two monoband antennas
2Conn – Each band has its connector. You can connect transceivers like IC-9100 on both 2m and 70cm bands with two cables.

 

With less than 100 W with this 2m70DX41-2Conn dual band antenna, you can work many EME stations.

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!
