70cm EME-DX 8m Boom Antenna 70cm30DX 432-434MHz

Low Side Lobes Excellent G/T 70cm EME-DX 8m Boom Antenna 70cm30DX. Equally good for UHF competitions or EME work. Easy to assemble and disassemble. This is a contest-winning antenna with superior performance, not calculated with EZNEC, which yields false performance and false G/T, but with the real and best possible gain and G/T calculated with state-of-the-art full 3D EM Simulation Software. Ideal for EME, Q65, and contests. The best G/T antenna compared to all other antennas in the boom length range up to 9 m.

With a stack of four antennas, it is possible to work EME even with 25W.

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, significantly outperforming those designed with 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 antennas and are mechanically constructed much better than any antennas from other manufacturers.
