Greases supplied


graisse_dxavenue_dxbeam.jpg2 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).
