70cm 23elements DX Antenna 70cm23DX 432-434MHz
Low Side Lobes Excellent G/T 70cm 23elements DX Antenna 70cm23DX. Good for stationary or portable use. Easy to assemble and disassemble. Even with a single antenna and 50W possible to work EME stations on the 70cm band. Equally good for UHF competitions or EME work. Although it looks similar, this is a completely different antenna compared to 70cm23DXA.

Antennas-Amplifiers Product Benefits. A Major advance in antenna design.
- F/B and G/T superiority.
All antennas have been calculated using state-of-the-art full 3D EM modeling 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 the EZNEC program.
- No tuning antennas.
Before dispatch, we assemble and test each antenna’s characteristics. No need to tune any element to get a perfect SWR on the intended frequency range. Everything is pre-tuned.
- Easy to set up.
Everything is labeled, just put a number to a number. Everything is included in the box: Antenna, balun, bracket, and guy rope support if needed. 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.

Azimuth radiation pattern is impressive.
I hope to participate with it in the 3. subreg contest soon.
Feeling with this Yagi is excellent.

In 3. sub regional contest. I used it in approx. 7,5 m agl. with 10 m coax H1000. I was very satisfied with the antenna, I was able to contact DX like OR6T or PA1VHF.
The SWR value was cca 1:1.05, which is the best value I have measured using different antennas ever before.
The radiation pattern is best as well.

Frede –
The antennas came as promised – very solid packed, quickly assembled without any problems. Must say they cannot be done better – super.
Today I removed old system and raised the new four antennas in “H” stack. Initial test seems to be fine. The horizontal pattern indicates that antennas are very very sharp – but that we knew.
Again thanks for all – communication, delivery, mechanical quality, electrical performance and fully recommendable.

I was able to be on for the June VHF contest with the antennas as noted previously. WOW. The 70cm23DX seemed to open the band on its own!! Running only about 100 watts, I was easily able to work a number of stations to about 300 km with ease. As noted with the other antennas, I was blown away by how quiet the antenna is; stations seem to just “jump” out of the noise floor. Very satisfied customer here. Next up, Horizon EME in the near future!
