4m 8elements Antenna 4m8DXP for Ultimate DXing

Super low noise 4m 8elements Antenna 4m8DXP designed for Top Notch Performance. Maximum gain, F/B, and SWR flatness. Antenna will give the key advantages in DX-ing. In pileups, everybody will know “Who Is The Boss” and to whom will be answered first DX station. Designed tapered elements and tapered boom to reduce wind load, and vibrations in the wind. 4m8DXP is very easy to set up. Everything is labeled, just put number to number. No need to tune any length or position of elements. All is already pre-tuned for perfect radiation pattern and SWR.

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 perfect SWR on the intended frequency range. Everything is pre-tuned.
• Easy to set up. Everything is labeled, just put number to 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.
