Information

The Daiwa Automatic Antenna Tuner model CNA-2002 marks an major advance amateur radio. For the first time, the radio amateur is offered a. high power automatic Antenna Tuner which will reduce the SWR to less than.1.5:1. This new development is made possible by Daiwa's advanced technology coupled with long experience.. in this field. FEATURES 1. Light, compact and high power Automatic.Antenna Tuner, the model -CNA-2002 is now available. In spite of it's small size, high voltage variable capacitors are equipped (TV 6kV). 2. A troidal core current transformer is used for the detection of Forward power and Reflected power. SWR measurement with very good frequency response between 3.5— 30 MHz is assured. 3. The unique Daiwa cross needle meter is fitted on the front panel. It can read Forward power, Reflected power and SWR at a glance. 4. A Pi network is employed as the Tuner circuitry which substantially, reduces harmonics radiation and TVI. (The band pass effect of the CNA-2002 is shown in Fig-12.) 5. Two Fine Tuning controls are equipped in parallel with main variable capacitors. These can be adjusted manually, to 1:1 SWR ratio, after the circuit has tuned automatically to the SWR of approximately 1.5:1. Variation of Antenna impedance at band-edges is easily compensated. 6. The built-in dummy load can be used for tuning the transmitter. (100W, 1 min. rating.).
