Measured perfect SWR in the whole band

2m 9Elements Lightweight Antenna 2m9DX5 Measured SWR

Horizontal Stacking Distances for F/S -12.5 dB lightweight antenna 2m9DXA:

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 2m9DXA

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

Antennas-Amplifiers Product Benefits:

  • 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.

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

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