Dual Socket Wattmeter
The Model 81021 Average Reading Dual Socket Wattmeter allows you to measure both Forward and Reflected RF
power with the flip of a switch. The Model 81021 uses standard Elements to accurately detect average RF power
from 100mw to 10 kW over 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.
and strong, the Model 81021 uses a heavy gauge metal case to protect the Wattmeter from impact shock and a
leather strap makes for safe and comfortable handling. For added convenience, two sockets for storage of
additional elements are located on the back of the unit.
Our use of a rugged shock mounted meter with a
mirrored-backed scale along with superior taut band technology provides reliable and accurate readings, plus the
integrity that satisfies both the US Navy and Canadian standards for bounce and vibration. This is your
assurance of complete accuracy.
Your confidence in the quality and dependability of Model 81021 is
assured with the Coaxial Dynamics Two Year Limited Warranty.
