Horizontal Stacking Distances for F/S -12.5 dB lightweight antenna 2m9DX5:

Two antennas: 3.15m. Gain 17.2 dBi (+2.9 dB)
Four antennas: 3.3m. Gain 20.2 dBi (+5.9 dB)

 

Vertical Stacking Distances for F/S -12.5dB low noise EME antenna 2m9DX5

Two antennas: 2.95m. Gain 17.2 dBi (+2.9 dB)
Four antennas: 3.05m. Gain 20.2 dBi (+5.9 dB)

 

Lower gain and a better suppression of all sidelobes. Sometimes good in urban (high noise) areas:

Horizontal stack 2.6 m for gain 16.93 dBi F/S< -18.7 dB
Horizontal stack 2.75 m for gain 17.04 dBi F/S< -16.5 dB
Vertical stack 2.5 m for gain 16.95 dBi F/S< -17 dB

Or anything between…

 

Lee WW2DX will use these 2m9DX5 and 2m12DX7 antennas on his extremely successful EME expeditions:

The antennas 2m9DX5 (PA144-9-5A) performed EXCEPTIONALLY well during the WORST EME conditions. Very impressive, congratulations!

The pair of 9’s are in the process of being installed in FN65 in Maine along the Atlantic Ocean for a 100% fully remote EME station.  Lee WW2DX

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 excellent 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 in a couple of minutes.
Everything is included in the antenna box: Antenna, balun with connector, and bracket. Yours is to assemble and have fun!

The old name of the antenna was PA144-9-5A
