The Bird 6154 Termaline RF Wattmeter that is designed to measure RF power under non-radiating conditions. The wattmeter is built around an accurate 50 ohm coaxial load resistor which becomes the transmitter load element, providing a practically reflectionless line termination from 25 to 1000 MHz. Power input to the load resistor is measured by a four-range crystal voltmeter reading directly in watts (5/15/50/150 W). A toggle switch determines the scale.

Features:

• Frequency Range:  25MHz - 1000MHz.
• Watts:  5/15/50/150.
• Ohms:  50
• Detector Diodes:  X1 and X10.
• Connector:  Type N-Female.
