3164-01 Open Boundary Quad-Ridged Horn

3164-01 Open Boundary Quad-Ridged Horn

Frequency Range: 100MHz – 1GHz ETS-Lindgren's Model 3164-01 Open Boundary Quad ridged Horn Antenna takes the open boundary concept to its extreme by providing a totally open horn, including an open boundary feed cavity. The model 3164-01 allows antenna engineers to perform measurements down to 100 MHz and up to 1 GHz with a single antenna. Its ability to measure two orthogonal polarized fields simultaneously means that it can be used to measure radiation patterns regardless of the orientation of the antenna under test. The 3164-01 brings the performance of the 3164 series horns down to 100 MHz. However, the antenna is not simply a scaled model of other horns in the series. To reduce weight and improve the low end performance the antenna was designed without an enclosed feed cavity. Although the feed cavity is not present, the antenna can still be mounted inside chambers; nested in the absorber or against a ground plane. The gain is not dramatically affected by the mounting scheme. Electrical Specification
