d) Hum and noise: Better than 40dB below rated output.
e) Harmonic Output Suppression:
1.8-21.5 MHz - better than 50 dB below rated output, 24-54 MHz - better than 66dB below rated output.
f) Input and Output Impedances:
- Nominal value: 50 Ohm unbalanced, UHF (SO239A) type connectors;
- Input circuit: broadband, VSWR less than 1.3:1, 1.8-54 MHz continuously (no tunings, no switching);
- Bypass path VSWR less than 1.1:1, 1.8-54 MHz continuously;
- Output (antenna) impedance matching capability: VSWR up to 3:1 or higher.
g) RF Gain: 13.5dB typically, frequency response less than 1dB (50-85W drive power for rated output).
h) Primary Power: 100-264 V (100, 110,120, 200, 210, 220, 230 & 240V nominal taps, +I0% -15% tol.),
50-60 Hz, single phase, 3500 VA consumption at rated output.
