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 con-
sidered effective. Most antennas have a VSWR of 1.5:1. For ex-
ample, 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.
W

Metropolitan Area Network which covers a city.
Wind loading A problem of antenna installation and operation.
