If an extension cable is added to move the antenna, what are the likely results?
- A. The likelihood of a direct lightning strike will increase.
- B. The data throughput rate will increase because VSWR will decrease.
- C. The Equivalent Isotropically Radiated Power (EIRP) will decrease.
- D. The size of the Fresnel zone will increase.
- E. The antenna's azimuth beamwidth will decrease.
Answer: C

NEW QUESTION 93
Your consulting firm has recently been hired to complete a site survey for a company. Your engineers use predictive design software for the task, but the company insists on a pre- deployment site visit. What task should be performed as part of the pre-deployment visit to prepare for a predictive design?
- A. Test several antenna types connected to the intended Aps for use in the eventual deployment
- B. Install at least one AP on each side of the exterior walls to test for co-channel interference through these walls
- C. Collect information about the company's security requirements and the current configuration of their RADIUS and user database servers
- D. Evaluate the building materials at ABC's facility and confirm that the floor plan documents are consistent with the actual building
Answer: D
