ADF 3500 System Prime Line/Navigation

This automatic direction finding system provides outstanding performance for aviation professionals who need excellent range andaccuracy as well as the ultimate in reliability. In addition to the standard frequency range of 190.0 kHz to 1799.5 kHz, the ADF 3500 alsoreceives the international maritime distress frequency of 2182 +/- kHz, making it suitable for search and rescue and other offshoreoperations. It is certified for high altitude operation in turbine powered aircraft.

The receiver is housed in a single compact unit, which complies with ARINC standards. It is light in weight and easy to install (DZUSmounted). Because of their efficient design and rugged construction, ADF 3500 systems have established an enviable record of trouble freeservice, even in the hostile environments of commercial and coast guard helicopters and in military aircraft installations.

Like all Becker Prime Line avionics equipment, the ADF 3500 systems combine modern technology and compact size to provide superiorperformance. Clear LCD displays, which are easily read in the brightest sunlight show both, active and preset frequencies.

Preselection of a standby frequency enables instant switch over to a second station for position fixing by cross bearings. The low profilecombined sense and loop antenna is suitable for mounting on high speed aircraft. Becker RMI converters are available to enable the systemto drive most types of indicators. Dependable optical/electronic, friction-free controls with excellent tactile feedback. Built-in test functionsperform a test routine immediately after the system is turned on, checking the receiver, microprocessor and displays.

The ADF 3500 systems are certified to the demanding requirements of applicable FAA TSO, JTSO, RTCA, EUROCAE and FTZspecifications.
