What is the intended use for the WLAN hardware known as a pole or mast mount unit?

A.

Mounting a lightning arrestor to a grounding rod

B.

Mounting an omnidirectional antenna to a mast

XYZ Corporation is experiencing connectivity problems with their existing building-to-building
bridge link. A concrete wall on the roof of one building is partially blocking the Fresnel Zone, and
the connection is dropping many frames. The administrator moves the antenna to an area not
obstructed by the concrete wall and then realizes the RF cable cannot reach the new location
If an extension cable is added to move the antenna, what are the likely results?

A.

The data throughput rate will increase because VSWR will decrease.

B.

The Equivalent Isotropically Radiated Power (EIRP) will decrease.

C.

The antenna’s azimuth beamwidth will decrease.

D.

The size of the Fresnel zone will increase.

E.

The likelihood of a direct lightning strike will increase.

When using an RF splitter to connect one transceiver to sector antennas loss is incurred. What is
this loss called?

A.

Conversion loss

B.

Through loss

C.

Active loss

D.

Intentional loss
