• Standard Mast size (mm)/(inch): 50/2 (55/2.25 or 60/2.50 optional at no extra cost)

 

Possible settings

#1  1.4:1 VSWR on 7.0 and 7.1 MHz - 1.7:1 on 7.15 - 2.2:1 on 7.2 MHz

#2  1.4:1 VSWR on 7.05 and 7.15 MHz - 1.8:1 on 7.0 and 7.2 MHz

 

Insulating Guying

This rotary dipole is supplied with two guys in polyester (longevity > 25 years), quick fastening system and guy clamp that will be fixed to the mast (about 70 cm above the antenna).

As an option, a self guying kit allows you to place the rotary dipole DXBeam at the top of mast (regardless of the height required for guying). It also allows the guying of the dipole to the ground (easier), and install the antenna without adjust the guys when antenna is up.

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).
