The Coaxial Dynamics Model 81021 is a versatile and reliable Average Reading Dual Socket Wattmeter designed for measuring both Forward and Reflected RF power over a broad frequency range. This wattmeter allows you to measure RF power from 100mW to 10 kW across a frequency range of 0.45 MHz to 2.3 GHz.
- Complete with an internal dual socket 7/8” Line Section and Quick Match RF connectors, Model 81021 offers the speed and reliability you expect from Coaxial Dynamics.
- A convenient front panel switch gives the user the ability to display Forward or Reflected power on the analog meter.
The Model 81021 is easy to use—no additional black boxes or delicate remote sensors are needed. Simply connect the wattmeter in-line between the RF source and the Antenna or Load, insert the appropriate elements, and select either the Forward or Reflected switch position. The RF power is visually identified directly on the large 4 ½” mirrored scale.
Versatile and strong, the Model 81021 employs a heavy-gauge metal case to protect the wattmeter from impact shock, and a leather strap ensures safe and comfortable handling. For added convenience, two sockets for storage of additional elements are located on the back of the unit.
- The use of a rugged shock-mounted meter with a mirrored-backed scale, along with superior taut band technology, provides reliable and accurate readings.
- This design integrity satisfies both the US Navy and Canadian standards for bounce and vibration, ensuring complete accuracy.
Your confidence in the quality and dependability of the Model 81021 Wattmeter is assured with the Coaxial Dynamics Two Year Limited Warranty.
