2. Antenna analyzer - Wikipedia

   en.wikipedia.org/wiki/Antenna_analyzer

   An antenna analyzer measuring SWR and complex impedance of a dummy load. MFJ-269, MFJ Enterprises Inc. An antenna analyzer or in British aerial analyser (also known as a noise bridge, RX bridge, SWR analyzer, or RF analyzer) is a device used for measuring the input impedance of antenna systems in radio electronics applications.

3. SWR meter - Wikipedia

   en.wikipedia.org/wiki/SWR_meter

   By analogy, the measurement cable is a crystal radio (non-discriminating receiver) representing all the radio receivers that might suffer interference from dirty emissions. Though called an SWR Meter, a low measured ratio indicates not only good match, but also clean A3, F3, or G3 emission without excessive harmonics nor spurious (out-of ...

4. Field strength meter - Wikipedia

   en.wikipedia.org/wiki/Field_strength_meter

   A field strength meter is actually a simple receiver. The RF signal is detected and fed to a microammeter, which is scaled in dBμ. The frequency range of the tuner is usually within the terrestrial broadcasting bands. Some FS meters can also receive satellite (TVRO and RRO) frequencies.

6. Standing wave ratio - Wikipedia

   en.wikipedia.org/wiki/Standing_wave_ratio

   In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide. Impedance mismatches result in standing waves along the transmission line, and SWR is defined as the ratio of the partial standing wave 's amplitude at an ...

7. Slotted line - Wikipedia

   en.wikipedia.org/wiki/Slotted_line

   Figure 1. Waveguide slotted line. Slotted lines are used for microwave measurements and consist of a movable probe inserted into a slot in a transmission line.They are used in conjunction with a microwave power source and usually, in keeping with their low-cost application, a low cost Schottky diode detector and VSWR meter rather than an expensive microwave power meter.

   [24] [25] [26] Introduced in the year 2000, the radio was known for its "all-in-one" functionality. It can transmit on all amateur radio bands between 160 meters and 70 centimeters, with the exception of the 1.25 meters band, and the "X" model also has built-in 23 centimeters band capability option. Kenwood discontinued production of the TS ...
