With this antenna setup. Stack of 3 antennas contest crew F1AAM, F6BKD, F1FIH and F2CT Wins F8TD Trophy 2021

In the picture are Bernard F6BKD/HB9AYX, Michel F1FIH, Jean Pierre F1AAM, and F2CT.
Excellent results with ODX of more than 1000 km.
Congratulations to the team.
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.

Guy F2CT –
Your 23cm43DXHDP (PA1296-43-3.6AUTHD) 3 x 43el stack on 23cm.
We won the F8TD trophée on SHF end of august 2021 with outstanding results and tropo DX over 1000km.

Mirce Z32ZP –
With this 23cm43DXHDP (PA1296-43-3.6AUTHD) antenna on IARU UHF/Microwaves contest i made ODX 797km QSO with OM3KII from North Macedonia with just 10W from Icom 9700 and 7m LMR400 cable. No preamplifier.
Very satisfied.
