Jack has purchased a semi-directional antenna and an access point from different vendors. They have been certified as a system by the FCC through a third party. What type of cables or connectors must be used as part of this system to connect the access point to the antenna?
  1. RF cable with industry standard connectors and a pigtail cable with appropriate connectors
  2. RF cable with N connectors and a pigtail with N connectors on both sides
  3. RF cable with SMA connectors and a pigtail with N connectors on both sides
  4. RF cable with connectors matching the access point and a pigtail cable with appropriate connectors for the antenna and RF cable connection
Explanation
Answer - D - Jack should use an RF cable with connectors matching the access point and a pigtail cable with appropriate connectors for the antenna and RF cable connection.

Key Takeaway: A pigtail cable is used to adapt two different kinds of connectors. Typically, one of the connectors is an industry standard type, such as an N type or SMA. Having the RF cable connector match the access point connector avoids buying separate adapter connectors, which insert more loss into the circuit. The pigtail cable will be attached to the RF cable and the antenna.
