Modular 7 ANT RX switch with controller and more RX outputs

This is modular 7 RX antenna switch. It allows you tu use up to 7 independant RX antennas (beverages, Bi-dir beverages, RX loops etc.). You can use just one board for single RX output or up to three boards for three independant RX. Also ANT ports can be open or connected tu dummy load. There is 50 or 75 ohms one and also LC BPF isolation for that for multi stations and Bi-dir beverages with two outputs. You can use controller with BPFs and preamp, protections and RX way switching. Also two independant RX per band are possible with optional 7 ANT RX SPLITTER.

This is ideal solution for Single OP through SO2R to Multi-Multi, with up to 2 independant RX per band!
