Abstract
A portable roll-out antenna system which forms a compact, transportable assembly when not being used. The roll-out antenna system is provided with flexible antenna elements which are individually wound onto reels for storage and transportation, and rolled out for use as an efficient antenna system. Each pair of antenna elements is connected to a balun for proper connection to unbalanced connecting cables. The baluns are housed in an end-cap assembly upon which are mounted the antenna element reels when the antenna system is not being used. A power splitter allows more than one connecting cable to be electrically coupled to a remote transmitter/receiver by way of a transmission line. The power splitter is housed in a center reel assembly which is provided with a component to lockably receive part of the end-cap assembly upon which is mounted the antenna-element reels, thus holding the antenna-element reels together and forming a compact, transportable assembly.
