The Ameritron ARF-1000 selectable low-pass filter is designed to reduce harmonics of transceivers or amplifiers.
It has a frequency select switch for six different cut-off frequencies up to 30 MHz. When a cut-off frequency is selected, the low-pass filter attenuates harmonics on frequencies significantly above the selected frequency.
The ARF-1000 will typically handle power levels of 1 KW PEP, 600 Watts CW, and 400 Watts RTTY. The power rating will vary with both load impedance and the equipment it is used with. SO-239 connectors for input and output.
