QC (quick change) type connectors and a full range of plug-in elements provide a wide choice of frequency ranges and power levels giving the Model 43 amazing flexibility. Two extra elements can be stored in the housing, one on each side.

Features
  • Accurate CW field power measurement over 450 kHz to 2.7 GHz and 100 mW to 10 kW
  • Uses industry standard Bird elements with space to store 2 additional within the meter housing
  • Rugged metal housing for the most demanding environments
  • Quick Change (QC) connectors to minimize the need for adapters when making critical measurements
