TriBand 2m 222MHz 70cm Antenna Two Connectors 2m222M70cm50-2C Two Connectors

World’s first TriBand 2m 222MHz 70cm Antenna Two Connectors 2m222M70cm50-2C with three antennas on the same boom. Super gain 2m 11 elements, excellent gain 12 elements on 1.25m 222-224MHz, and good gain 27 elements 70cm 432-432MHz for DXing, contesting, and EME. Superb, universal antenna for a limited space or one-man contesting.

With two antennas in a vertical stack, you can achieve remarkable gain on all three bands. 17.5 dBi on 2m, 17.35 dBi on 1.25m, and 18.8 dBi on 70cm for easy EME or contesting, even with 100W. The 2m antenna has a similar performance to our excellent Low Noise Yagis, with the best G/T for its length 2m11DXP.

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