Operating Frequency Range
- Continuous from 1.8 to 30 and from 50 to 54 MHz;
- Extensions and/or changes on request;
Minimum Range of the Matched Impedances (at Each of the Four Antenna Outputs)
- All impedances with SWR from 1:1 to 3:1 towards 50 Ohm, any phase angle, unbalanced input and output;
- For some frequencies and impedances, matching is possible at SWR above 3:1 at the antenna output (up to 10:1), but the maximum allowed power is reduced;
Maximum Allowed Input Power (PEP, Mean or Continuous Carrier, Without Mode Limitation)
- At antenna SWR below 2.5: 1500 W;
- At antenna SWR between 2.5 and 3: 1200 W;
- At antenna SWR between 3 and 5 (provided matching is possible): 500 W;
- At antenna SWR between 5 and 10 (provided matching is possible): 200 W;
- Operation with SWR above 10:1 is not allowed;
RF Input Characteristics
- Rated impedance: 50 Ohm unbalanced;
- Input connector type: UHF/PTFE (SO-239A);
- SWR during full tuning (basic cycle): No higher than 2:1;
- SWR immediately after full tuning: No higher than 1.5:1 (1.3:1 typically);
Antenna Outputs Characteristics, Antenna 1 to Antenna 4
- Rated impedance: 50 Ohm unbalanced;
- Maximum antenna output SWR: 3:1 (up to 10:1 with RF power limitations;
- Output connectors type: UHF/PTFE (SO-239A) - 4 pcs;
Full Tuning Duration (Basic Cycle)
Basic cycle for preparation of user full tuning settings, with automatic storage in the non-volatile memory:
- In the range of 1.8 to 10 MHz: No more than 5 seconds (2-3 seconds typically);
- In the range of 10 to 54 MHz: No more than 3 seconds (1-2 seconds typically);
Input Signal Needed to Prepare User Tuning Settings
- Non-modulated carrier power 25 W +3/-3 dB (12.5 to 50 W);
Power Supply
- +26 VDC, +10/-15%, consumption of 25 W at most;
- Supplied by an amplifier of the ACOM transistor series over the input RF coaxial cable;
Remote Control
- The remote control and indication from an amplifier of the ACOM transistor series is provided over the input RF coaxial cable of the tuner using a 60 kHz / 4800 bps bidirectional FSK modem;
Maximum Length of the Input Coaxial Cable
- The maximum length of the RF coaxial cable between the amplifier output and the tuner input is 100 m (330 ft) for a cable of RG213 type or similar. The cable characteristic impedance should be 50 Ohm and the DC resistance should be below 1 Ohm for inner and outer conductors altogether;
Size & Weight (operating, excluding fastening elements and connected cables)
- WxDxH: 345x250x190 mm, 4.2 kg (13.6x9.9x7.5 inches, 9.3 lbs.);
Shipping Size & Weight
