Appropriate for military, civil and maritime communication use;   either on control centers or coastal stations.

antenna AT 111 W 1 - Antennas and couplers NAVTEX


Ref.: AT-111-W

This antenna is designed for communication applications in the range from 100KHz to 1.6MHz, for its use in maritime coast stations, aviation communications as well as all type of communications in telegraphy, telephone, etc.. in the range of the H.F.

It is made of fiberglass and installed self-supported with no struts, obtaining high performance in wind resistance and adverse climatological conditions.
A complete radiant system of great efficiency can be formed when combined with the AC-160-W antenna coupler. The antenna must be executed in its installation with a good ground to obtain better efficiency.

The antenna supports itself by twelve stainless steel esparragous fited in a concrete base or other anchorage capable of supporting the weight of the antenna (135 Kg.) and the weight originated by the wind ion the antenna. This antenna has a chargue coil inside the fiberglass which forms part of the second section with the intention of making easier its coupling and increase the editing efficiency.
