This document is a detailed technical drawing for a Cable Assembly, RF 14-Elem Array: Heliax, issued by the Department of Transportation's Federal Aviation Administration. The drawing specifies a cable set consisting of 28 cables built to precise specifications, with cables ranging from 52 to 54 feet in length. Key technical details include:

The cables are designed with specific connector requirements, including TED type 7-30-72 - 90° connectors for Commscope (Andrew) 1/4" Heliax cable. Each cable has unique labeling instructions, with connectors to be installed on specific ends and heat shrink components applied according to strict guidelines. The cable set is intended for direct connection to a distribution unit, with an optional 90-degree cable length to bypass existing cables. After assembly, the electrical length of the reference cable must be measured at 108 MHz using a vector voltmeter and signal generator, with specific tolerances for cable length variations.
