For our tubes we have used the best alloy available for the construction of antennas, the AW6063-T66 alloy of Aluminum, Magnesium and Silicon tempered to the T-66 state which gives the stylus exceptional resistance, which is achieved by extrusion and subsequently cold drawn. Our tubes are extremely precise on both diameters, and also on the thickness of the wall, allowing for precise coupling and with less “play” between the tubes.
The “Ground Plane” is composed of 4 sturdy radials of length 1.4m, “Full-Quarter Wave” made of single section tube with diameter and thickness respectively 13×1.25mm which are fixed to the support plate by means of two U-Bolts and self-locking nuts. In the fixing area 4 fiberglass reinforcements are provided which strengthen the joints and prevent the crushing of the tubes.
Because an antenna that accepts high power is a more efficient antenna, otherwise it would tend to heat up due to the Joule effect and dissipate a significant part of the applied RF power into heat, which happens with most competing products, but which unfortunately users cannot test due to a lack of adequate equipment and instrumentation.
