Super Gain 6m 9elements Extreme Strong Antenna 6m9DXEXSHD

Ultimate 6m 9elements Extreme Strong Antenna 6m9DXEXSHD devoted for any harsh environment. Norway winter, the North Pole, or Hurricane Katrina cannot harm this antenna. An almost 12m boom will ensure the best gain, extremely low sidelobes, and the ability to easily hear weak signals.

This antenna is constructed with the same boom and element sizes as our heavy-duty HF antennas.

Everything is labeled on the antenna, just put number to number. No need to tune any length or position of elements. All is already pre-tuned for the perfect radiation pattern and SWR. Maximum power input is 8000W for the price. Look down for a reduced version of 3500W or 1500W.

The old name of the antenna was PA50-9-12BGEXSHD.

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 attributes 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!

 

DK8NE tested the antenna hanging from a cherry-picker.

 

Return Loss (SWR) test

 

 

What a beast and how the antenna is on point, even hanging from a cherry-picker. Great work.
Mny tnx again!

Antenna will go to my QTH on the mountain in about 2 or 3 weeks. I am looking forward to testing it from there!

73s, Uli DK8NE
