Materiali
The best material available in the Italian, German and United Kingdom markets have been chosen for the mechanical construction of the boom and any other antenna-accessories. All antenna parts are assembled and tested exclusively by Ultra Beam.
The boom tubes are made of 6082 T6 aluminium type chosen for its very good mechanical characteristics which is by 40 % superior to the custom aluminium and even by 10% superior to the well-known 6061 T6 Type.
A double-boom has been adopted for the 4 element antennas. This system increases a lot the torsion-resistance by very little additional weight .
The mast to boom plate is made of solid pre-drilled 6 mm inox steel !
Special design to achieve the best weight to mechanical resistance ratio !
Antenna- and stepmotor-housings are made of high quality ABS with an extra UV resistant PMMA coating !
