Especially for areas with a harsh climate in the Far North, two-dipole antennas were developed. The antennas are made of all-welded construction with an internal addition system and offered in two models: aluminum (A) and stainless steel (S) for harsh Arctic conditions.
Thanks to modern computer modeling and measuring instruments, these antennas have a very wide band as agreed (see diagram), which has a positive effect on the quality of communication during icing. Each copy of the antenna before shipment passes the output control at factory.
