• 50.000 - 54.000 MHz (6 m band)*
• 70.000 - 70.500 MHz (4 m band)*
• (*) Please, refer the applicable regional band plans and laws for specific allocations and limitations;
• In specific business cases, extensions or changes of the frequency coverage can be discussed, but this must be agreed upon before ordering. In any case, this is not the producer's obligation and can not be against local rules and laws.

Rated Output Power

• 500 W ±0.5 dB, PEP or digital;
• You will have to reduce the output power to about 300 W in order to keep the mains current consumption below 12 A if the amplifier is operated at below 200 VAC mains supply voltage.

Intermodulation Distortion (IMD3)

• Better than 30 dB below rated PEP;

Harmonic and Parasitic Emissions Output Suppression

• Below 30 MHz - better than 50 dBc below rated output;
• Above 30 MHz - better than 70 dBc below rated output;

Input Impedances

• Nominal value: 50 Ohm unbalanced, UHF (SO-239A) type connectors;
• SWR: Below 1.5 (1.2 typically), 1.8-70.5 MHz continuous range;
• RF bypass: SWR - below 1.1, 1.8-70.5 MHz;

Antenna Impedance

• Nominal value: 50 Ohm unbalanced;
• Two antenna outputs available:
• RF OUTPUT 1 output has to be used for direct connection to ACOM antenna tuners 04AT or 06AT only. ACOM antenna tuners 04AT and 06AT support antennas within 160 to 6 meter bands;
• RF OUTPUT 2 output has to be used for direct connection to antenna or to non‑ACOM antenna tuner. A well-matched antenna with an SWR below 1.5 can be connected to this output for any band. While low SWR is good for any band, it is extremely important on 6 and 4 m;
• Antenna connectors: PTFE UHF (SO-239A) type;

RF Power Gain

• 11.7 dB ±1.5 dB (typically 35 W drive for rated output);

Mains Power Supply Voltage

• 100-240 VAC ±10%, 50-60 Hz, Single phase;

Mains Power Consumption at Rated Output Power

• Up to 1000 VA;
• Power factor at rated output: 0.95 or higher;

Mains Power Consumption in Low Energy (Waiting) Mode

• Less than 1 VA;

Safety and Electromagnetic Compatibility

• Complies with CE safety and electromagnetic compatibility requirements, as well  as with the US Federal Communications Commission (FCC) regulations;

Size & Weight (operating, excluding connected cables)
