How to Use: To use the Wattmeter, simply connect it between the transmitter and antenna or dummy load, and plug in the appropriate measuring element. The RF power is directly displayed on the 4-1/2″ triple scale meter. The external Line Section can be used up to 200 feet from the meter with the permanently attached DC cables (10-foot normally supplied).

Rugged Construction: The meter unit is protected by a rugged, shock-proof housing, ensuring durability in various operational environments. For added convenience, two sockets for storage of additional measuring elements are located on the back of the unit.

The 81100-A series meets both US Navy and Canadian standards for bounce and vibration, ensuring accuracy in challenging conditions. This series provides a reliable solution for high-power directional RF power measurements.
