V
VSWR (Voltage
Standing Wave
Ratio)
VSWR is the voltage ratio of minimum to maximum across a
transmission line. A VSWR of 2.0:1 or less in an antenna is
considered effective. Most antennas have a VSWR of 1.5:1. For
example, when using a radio with a four-watt output with an
antenna VSWR of 1.5:1, the reflected power will be 160 milliwatts.
VT 100 A terminal emulation system.
