SIP360 Antennas and Transmission Lines

The understanding of antennas and transmission lines is an integral part of any telecommunications course. This course includes a microwave transmitter, field-strength meter, Lecher line and detector panel; horizontal and vertical dipole and Yagi antennas, to provide both theory and hands-on experiments in antenna radiation patterns, polarization, gains and VSWR measurements. The course provides for 60 hours of instruction.
