Boom guy set → new August 2014
1 - "Over the boom" guy set with vertical support included : Due to the weight and size of the 5 element 20m beam, an "over the boom" guy set providing vertical support is now included. The set consists of a reinforced tube (1m long, 50mm in diameter and 5mm wall thickness) to which the 7.5mm non-metallic tensioning cable (CU1) attaches. (see pictures above).
Tensioning is done whilst the antenna is at ground level, ie. prior to its installation on the mast/tower.2 - Lateral guying to the boom recommended : Should you live in a region where wind, snow or ice are common place, we recommend adding lateral guying to the boom. This addition could also be of interest to those who have towers without tower tram systems. It prevents the boom from being subjected to unnecessary mechanical stress during its installation. If you choose to add this diamond shaped guying yourself, be sure to do so using non-metallic cables.

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).
