SOLD! USED BIRD WATT METER

FANTASTIC BIRD WATT METER COMPLETE WITH CARRY CASE & VARIOUS SLUGS

Bird® offers a wide selection of portable insertion-type instruments for measuring forward and reflected power in coaxial transmission lines. Thruline instruments can be left in the line for continuous monitoring of either the transmitter power output or the amount reflected by the antenna.

These two qualities are actually the most important transmission parameters: Tuning for the minimum reflected power results in a good match of the load (antenna) to the line, and adjusting the transmitter for maximum forward power into a matched antenna approaches ideal design goals, These optimum system adjustments result in a low Voltage Standing Wave Ratio.
