Which statement about CDL (Common Data Link) is true?

• A. Setup via TAC-D 5 and has two directional antennas plus one omnidirectional; disabled by WOW switch on the ground.
• B. Provides only video feed and is unencrypted.
• C. Has no pre-designed networks.
• D. Is a HF data link.

Answer: (A)

CDL is a line-of-sight data link that is configured and controlled through the TAC-D 5 console, with a terminal setup that uses two directional antennas plus one omnidirectional antenna to maintain a reliable link as the platform moves. The WOW switch on the ground provides a quick way to disable the link when needed, such as for safety or security reasons. This combination—TAC-D 5 configuration, multi-antenna arrangement for robust, directed coverage, and a ground-based disable switch—is characteristic of how CDL terminals are operated.

Other options don’t fit because CDL isn’t limited to a video feed or unencrypted, and it supports more than a single, simple connection. It isn’t an HF data link, and the system is designed around predefined network configurations rather than having no networks at all.
