PPT-Antennas

Baluns A balun is a device to match a balanced antenna to unbalanced transmission line such as coax Used eg to connect a dipole antenna to a 50 ohm coaxial cable where it would be installed .

Interferometry. . Rick . Perley. (NRAO-Socorro). Recap, and Plan. Dave has shown you why determining the full polarization state of natural radiation is important. . In this lecture I describe how an interferometer determines the Stokes parameters for distant sources. Antenna Testing. Getting Ready to Test. Whenever possible you want to adjust the antenna in place on it's mounting structure. In this way you are taking the structure and other unavoidable local objects into consideration. 160 and 80 Meter Antennas . for the Declining Solar Cycle. Vertical polarization on 160 meters.
