The antenna could be produced in several versions:

  • SKU: 1320 2m70cm34DX-2C (The old name PA144-432-34-6-2CBGP) 144-145, 432-434
  • SKU: 1330 2m70cm34DXA-2C 144-145, 432-434. Expedition version with parts up to 1.2m
  • SKU: 1335 2m70cm34WB-2C 144-146, 432-440. EU Wideband version
  • SKU: 1340 2m70cm34Wide-2C 144-148, 430-450. USA Wideband version. Region 2

 

What does 2m70cm34DX-2C mean?

  • 2m – 2m band with low SWR and excellent gain and G/T
  • 70cm – 70cm band with low SWR and excellent gain and G/T
  • 3434 elements. 11 Elements on 2m and 23 elements on 70cm
  • DX – Covers DX part of the bands or wideband versions
  • 2C  – Two connectors for each band

 

EME with just 100 W will be enough to start working with a lot of amateurs around the world on both bands.

A system with two vertically stacked antennas at 2.55m could achieve about 17.35 dBi at 144 MHz and about 20.8 dBi at 432 MHz. Enough for EME or contesting.

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 antennas and are mechanically constructed much better than any antennas from other manufacturers.

 

All 2 meter / 70 cm antennas: 2m/70cm antennas
2m / 70cm Common Connector antenna
2m / 70cm Two Connector Dual Band

  1. Ken

    Keep up the great work you and your team are doing, fantastic products.
    Company Antennas-amplifiers is the only manufacturer of VHF + UHF antennas I would use for build quality and performance.
