Non-Directional RF Power Sensors
Measures output power of either analog or digitally modulated radios up to 125 watts.
4044 Series Non-Directional Power Sensors are designed to be used for continuous power monitoring in multiple Land Mobile Radio (LMR) systems when used with the Bird 3141 Channel Power Monitor (CPM). The 4044 sensor is typically used to measure forward average power on a 50 ohm RF transmission line with a maximum 125 watt forward power level in a frequency band with an overall range of 118 to 960 MHz.
Product Features
- Economical and capable of measuring the output power of either analog or digitally modulated radios up to 125 watts.
- Accurate to within +/-5% of reading with traceability to NIST.
- Non-directional and ideal for use at the input to each channel of the transmit combiner where the VSWR is well controlled.
