Description
The Bird Wideband Coupler is a short length of line section with two directional couplers, allowing the RF
power in the line to be sampled with the Bird 5011 Terminating Power Sensor (TPS). Couplers are available
for either UHF or VHF operation in a variety of line sizes and power ratings.
To provide accurate power readings, the Wideband Coupler is measured across its frequency band to
determine the exact coupling factors. These are provided on a label on the back of the unit.
