Log periodic aerials have an extremely linear frequency response, an excellent Front/Back ratio and a radiation diagram with very reduced side lobes. The F connection patented system allows the best exploitation of the electrical features of the aerials decreasing to the minimum attenuations and breaks in continuity due to the traditional connection with clamp. They are completely realized in aluminium special alloy. They are supplied completely pre-assembled.
Emme Esse Patents Antennas made of aluminum alloy without antioxidant treatment.
