Our T1915KT series is used for mounting an entire sector of antennas without penetrating the surface of a rooftop or other horizontal structure. We offer an almost unlimited range of multi-mast configurations to suit virtually any non-penetrating sector frame application you require. Concret blocks can be used as ballast to anchor the frame. Our kit includes four rubber mats. The frame material is hot dipped galvanized steel. Related products: T1721 series pipe mounts, T3600MTP4 rubber mats.
