2m 70cm Full Band Coverage DualBand Antenna 2m70cm30WideAP 144-148 and 430-450MHz

Lightweight construction 2m 70cm Full Band Coverage DualBand Antenna 2m70cm30WideAP with 30 elements for ITU Region 2 – USA. 9 active elements on 2m and 21+1 on 70cm. Very handy boom length of about 4.5 meters. Does not need guy rope support for stationary use. This antenna features high-quality construction and is easy to assemble, making it suitable for portable use and two-band contesting with a single transceiver. Utilizing two or four antennas in a stack is very efficient for competitions and EME communications, enabling easy Moon Bounce on a single call across both bands.

 

Key Features

• Lightweight construction for a 4.5m long antenna and 30 elements. Just 5kg
• Single (common) connector for both bands
• Broadband design with all elements diameter 8mm, including 70cm elements
• Excellent Gain on 2m: Up to 13.9 dBi.
• Excellent Gain on 70cm: Up to 17 dBi.
• SWR less than 1.2 on any frequency from 144 to 148MHz.
• SWR less than 1.2 on any frequency from 430 to 450MHz.
• Maximum power on 2m: 750W
• Maximum power on 70cm: 700W
• The antenna covers the (Private Mobile Radio) PMR446 band.
• Robust Construction: Built on a tapered 4.5m boom (using 20×20, 30×30, and 20 x 20 mm boom sections)
• The antenna is not calculated using EZNEC, which yields inaccurate performance, but is calculated using advanced state-of-the-art full 3D EM modeling software to achieve the best possible gain, including the influence of the boom, bracket, balun, and connector.

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 our antennas are the world’s strongest and are mechanically constructed far better than those from other manufacturers.
