Practical Antenna Handbook 5/e, 5th Edition

CHAPTER 27Testing and Troubleshooting

This chapter examines some of the instruments and techniques for testing antenna systems—whether brand-new installations or when trouble crops up on existing antennas. Figure 27.1 shows in block diagram format a basic radio system capable of two-way communication. We have specifically limited the diagram’s level of detail so the only interconnections shown are those that carry RF signals and/or transmitter power between the various station components: transmitter, receiver (or transceiver), amplifier, T/R switch, wattmeter/SWR bridge, low-pass filter, impedance-matching unit, and the antenna itself. All of these interconnections, whether long or short, are lengths of transmission line. Today, in almost all ...
