Connecting RF Power

Insert the Bird APM-16 in 50 ohm coaxial transmission lines. The RF source can
be connected to either side of the wattmeter.

Absorption Wattmeter

Combining the Thruline Wattmeter with a Bird Termaline Load creates an accu-
rate absorption wattmeter. With this combination, readings only need to be
taken in the forward direction because the reflected power will be negligible.
