Abstract
Abstract A switching matrix including an orthogonal array of m X n coaxial lines, where m equals the number of transmitters which may be simultaneously connected to the matrix and n is the number of antennas to each of which any one of the m transmitters may be connected. Each of the n rows is made up of m separated sections of a coaxial line center conductor connected electrically by first conducting contacts at each cross-point of the matrix. Each of the m columns is made up of n separated sections of a coaxial line center conductor connected electrically by second conducting contacts at each cross-point of the matrix. The first and second conducting contacts for each cross-point are a part of a common rod separated by segments of insulating material. A cross-point through connection is established by movement of the rod so as to connect the row to the column by relocation of the second conducting contact. Simultaneously the remaining length of the row and column are automatically grounded by the first conducting contact and a third conducting contact separated by insulating material from the second conducting contact to eliminate the presence of residual stubs in the matrix. A cam assembly to make and break the cross-point through connection is coupled to either all the rods of a column or all the rods of a row depending upon which has the lesser number of rods. A single motor drives the cam assembly.
