ANTENNA COUPLERS
Antenna couplers ATU-500 and ATU-1000
Antenna couplers ATU-500 and ATU-1000 are designed for conditioning output of radio transmitter and antenna at frequency range 1,6…30 MHz. It provides a transformation of complex input antennas resistance into an active burden resistance of radio or power amplifier that is 50 Ohm at SWR 1,4…2 at work frequency range.
Used with radio station Micom-1 и Micom-2 in SW range for work in extreme situation, tubing protection, etc.
Technical characteristics:
- Frequency range: 1600…30000 kHz
- Leading power: 500 W (ATU-500) and 1000 W (ATU-1000)
- Input resistance of tuned device: 50 Оhm with SWR < 1,4
- Tune time of antenna coupler: no more than 3 с
- Supply voltage/current: +24 V DC /2 А
- Work temperature range: -20…+50ºС
