PURPOSE AND STRUCTURE
Antenna is used for application in the systems of radiobroadcasting at OHS range or PM subrange (66-74 MHz.), or at FM sub range (88-108MHz.)
Structurally antenna is an array antenna, made of loop vibrators. Vibrators are made of brass, and the bearing is made of steel or aluminum alloy materials. From external actions the feed node of loop vibrators is protected by radiotransparent covering.
Antenna is installed on the top of the tower or on the roof of a high building on the own metalware (due to the structure of antenna elements it is also possible to assemble them on the customer’s pipe 60-110mm in diameter).
