- (*) Please, refer the applicable regional band plans and laws for specific allocations and limitations;
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 European Union’s CE safety and electromagnetic compatibility requirements;
- Complies with the US Federal Communications Commission (FCC) regulations – FCC Identifier: 2AJXZ500S, Date of Grant: 19 April 2023;
