ETS-Lindgren 3147 Log Periodic Dipole Array Antenna - Manual (Page 30)

Typical Antenna Pattern for 200 MHz and 300 MHz
This shows a sample antenna pattern taken at selected frequencies of 200 MHz
and 300 MHz. Additional antenna patterns are located in Appendix A on page 41.
These patterns were measured indoors using a separation distance of 1 meter to
1.5 meters between the transmit antenna and the receive antenna.
The antenna patterns in Appendix A and the beamwidths on page 26 are useful
in determining the size of the Equipment Under Test (EUT) that can be measured
with the Model 3147 at a specified distance.
