Product details


Wide Bandwith Directional Thrueline Wattmeter​.
The 4304A is an insertion-type RF wattmeter, designed to measure RF power levels and load match in 50-ohm coaxial transmission lines (VSWR) using just one element, already included.

4304A, Fixed 25-1000 MHz 5-500 Watt Element, Wattmeter uses the basic construction of the Model 43 and modifies it with a special broadband element and range switch for general purpose RF power measurement without the hassle of carrying a set of individual elements.

  • Fixed 25-1000 MHz, 5-500W, Portable Wattmeter
  • Uses a Single Broadband Element with a 5-position Range Switch
  • Same rugged metal housing as the Model 43
  • Quick Change (QC) connectors to minimize the need for adaptors when making critical measurement
