The new ruggedized heavy-duty weather-proof antenna Tuning Unit is made of die-cast silumin and thus constructed in accordance with the harsh environment in which it has to operate for years without maintenance. The white colour secures optimum thermal emission/absorption ratio. Connection from the Antenna Tuning Unit to the
Transceiver Unit for RX/TX signals, data communication and DC supply is made by one single coax cable.
The operator will not feel the change in antenna characteristics normally taking place during
changing weather conditions, as the microprocessor technology ensures extremely fast tuning under all conditions and the accurate tuning
ensures optimum transmission of power through the antenna.
