Page 12: Chapter 1 Introduction
The silver plated brass RF line section is precision made to provide the best possible impedance match to the coaxial RF transmission line in which the wattmeter is inserted. At each end of the line section are Bird Quick-Change type RF connectors, which may be quickly interchanged with any other Bird “QC”... -

Page 14: Theory Of Operation
Directional RF Thruline® Wattmeter, Series 4410 Theory Of Operation On any uniform RF line section there are voltages, currents and standing waves present when RF power is applied. These are the results of two traveling waves, forward and reflected. The characteristic impedance of these lines is a pure resistance, usually 50 ohms for useful lines. -
Page 15: Chapter 2 Installation
Chapter 2 Installation Portability When transporting the wattmeter, be sure the range switch is in the “off” position. In any other switch position, there is a slight drain on the 9 V battery. If the unit is to be inactive for more than 2 weeks, remove the battery to avoid damage from possible battery leakage. -
Page 16: Inserting In Transmission Line
Directional RF Thruline® Wattmeter, Series 4410 Inserting in Transmission Line WARNING Exposure to RF power radiation and the possibility of RF shock or burns exist under some operating conditions. Always turn off transmitter when connecting or disconnecting wattmeter. Be sure transmission line is terminated into a load or antenna. -
Page 17: Chapter 3 Operation
Operation Connectors The Series 4410 Wattmeter is normally supplied with two Female N type connectors which are of the Bird Quick-Change “QC” design. Other “QC” connectors are available as listed in the "Replacement Parts List" on page 22 Inserting Elements The plug-in element is inserted into the line section socket and rotated to either stop. -

Directional RF Thruline® Wattmeter, Series 4410 RF Power Measurements WARNING Exposure to RF power radiation and the possibility of RF shock or burns exist under some operating conditions. Always turn off transmitter when connecting or disconnecting wattmeter. Be sure transmission line is terminated into a load or antenna. -
Page 19: Zero Meter
Operation Zero Meter Before any power measurements are made, be sure the pointer rests on the zero mark. If not, set range switch to OFF position and adjust the zero adjustment screw clockwise or counterclockwise until the pointer rests at the zero mark. -
Page 20: Power Range Coverage
This correction is negligible (less than 1 percent) if the load has a VSWR of 1.2 or less. The Series 4410 Thruline Wattmeter used with a Bird Termaline Load Resistor of proper power rating forms a highly useful absorption wattmeter. Since the reflected power will be negligible, it will be unnecessary to rotate the element from the forward direction. -
Page 21: Determining Vswr
Operation Determining VSWR The Series 4410 Thruline Wattmeter is not designed to provide direct VSWR readings. However, VSWR readings can be determined very easily by using the provided graphs: Following the vertical and horizontal grid, determine intersection of forward and reverse power values. Slanted lines passing closest to this point indicate VSWR. -

Page 23: Performance Notes
Operation Performance Notes The Series 4410 wattmeter is sensitive to the presence of amplitude modulated signals and this can affect the accuracy. However, small amounts of AM (up to 10%) are tolerable, but for every 1% of AM, the inaccuracy of the reading may increase by up to 1% beyond the rated accuracy. -
Page 24: Chapter 4 Maintenance
Chapter 4 Maintenance The Series 4410 Thruline Wattmeter is of very rugged construction and requires little care and maintenance. Maintenance of the wattmeter is normally limited to cleaning. The amount of cleaning necessary can be minimized by keeping the plug-in element or the shipping slug in the socket of the line section. -

Page 31: Calibration Environment
Allow all the equipment and the instrument to be calibrated to completely stabilize with respect to the environment of the work area (specified above). The Series 4410 Wattmeter to be calibrated and the Bird Model 4410-070 calibration element may require up to 24 hours for complete environmental stabilization if brought from an extreme storage environment. - Page 32 Directional RF Thruline® Wattmeter, Series 4410 Note: The wattmeter does not need to be connected to the cali- bration setup for the five minute warm-up period. 5. After the equipment has stabilized, check the battery in the wattmeter by momentarily placing the range switch in the BATT position. The meter pointer should travel well into the “BATTERY TEST”...
