• Question 72:

  Given: 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.

  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.
  B. The Equivalent Isotropically Radiated Power (EIRP) will decrease.
