Load impedance: 52 Ω
Frequency range: 2 to 30 MHz with SWR: <1:1.3 @ 230 MHz (may also be used above
30 MHz to 230 MHz as a power indicator with no statement of power accuracy).
Wattmeter ranges: 0/15/50/300/1500 WPower for warning light is funished by a 120 VAC line.
Load resistor may be oil cooled without hermetic sealing, depending on type of oil this might be a health hazard if "PCB" based.
