What term describes the effect of increasing the intensity of an RF wave with an antenna by focusing the
energy in a specific direction?

What can cause an excessively high VSWR (Voltage Standing Wave Ratio) in a WLAN RF transmission
line?

What word describes the bending of an RF signal as it passes through a medium of a varying density from
that of free space?

What statements about the beamwidth of an RF antenna are true? (Choose 2)

When replacing the antenna of a WLAN device with a similar antenna type that has a higher passive gain,
what antenna characteristic will decrease?

In a long-distance RF link, what statement about Fade Margin is true?

A WLAN transmitter that emits a 200 mW signal is connected to a cable with 3 dB loss.
If the cable is connected to an antenna with 10 dBi gain, what is the EIRP at the antenna element?

What factors are taken into account when calculating the Link Budget of a point-to-point outdoor WLAN
bridge link?

Return Loss is the decrease of forward energy in a system when some of the power is being reflected back
toward the transmitter.
What will cause high return loss in an RF transmission system, including the radio, cables, connectors and
antenna?

As an RF wave propagates through space, the wave front experiences natural expansion that reduces its
signal strength in an area. What term describes the rate at which this expansion happens?
