Coaxial Dynamics 81050 Broadband Multirange RF Wattmeter

Covers from 25-21 MHz and up to 500 Watts. No need for multiple elements.

Unbelievable value for the small amount of money

   With the Model 81050 Directional Wattmeter you can now measure RF power in 50-Ohm coaxial cable and transmission lines without the need for additional plug-in elements. Model 81050 comes complete with the same 4-1/2" taut band meter movement, Quick Match RF Connectors, and precision line section that are used in our Model 821-A and 83000-A Wattmeters. These features plus a special non-removable Broadband Element allow full-scale power measurement on any one of 5 selectable ranges of 5, 15, 50, 150, and 500 watts across a frequency range of 25 to 21 MHz.

   Versatile and reliable, the Model 81050 is also easy to use. Simply connect the Wattmeter between the transmitter and the antenna or dummy load, select the appropriate power range on the 5 position switch, and read the power directly on the mirrored backed meter when the frequency is between 100 and 21 MHz. Below 100 MHz, multiply the meter reading by the correction factor found on the chart on the back of the Wattmeter. The use of a rugged shock mounted meter with a mirror-backed scale along with superior taut band technology, provides reliable and accurate readings, and also 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 the Model 81050 Wattmeter is assured with the Coaxial Dynamics Two Year Limited Warranty.
