Introduction
With this large 9 element 50 MHz antenna, DXBeam wanted to meet the requirements of the most demanding DXers on the 6m "Magic Band".
The boom (13.5m long) is guyed with non-metallic tension cables (longevity>25 years) consisting of 8 "over-the-boom" cables and 4 lateral cables. It also prevents any unnecessary mechanical stress to the boom during installation.
This new DXBeam antenna has been tested during 2 years by Patrick, F2DX (DX AVENUE, manufacturer of DXBeam antennas) who could instantly compare with an existing 7 element DXBeam normally used at his station.
On-the-air tests have shown this antenna's performance to be really excellent. This is more noticeable when signals are weak or almost inaudible on the 7 element Yagi (eg. on Ascension Island beacon ZD8VHF/B).

Greases supplied
2 kinds of grease are supplied with your antenna:
• Aluminum contact grease: Professional grease containing 30% aluminum particles, recommended for the assembly of aluminum antenna tubes. Prevents binding, corrosion and the formation of aluminum oxide, and allows easy dismantling of antennas after several years.
• Copper conductive grease: Professional conductive grease with a copper base, recommended for all hardware requiring a sound and lasting electrical contact. Prevents oxydisation, damp ingress, and limits chemical reaction between stainless steel and aluminum.
Balun or no Balun ?
• This antenna does not require any balun.
• To avoid having stray current on the braid of a coaxial cable (often the cause of RF and/or TVI/BCI), you can make your own 1:1 choke balun with coaxial cable. Explanations are provided with antenna assembly instructions. (See also our F.A.Q).
