Too many signals on different bands and tired of manually changing feed lines? Mini-circuits has a nice line of RF Matrix Switches that are USB controlled. I recently acquired a USB-4SPDR-A18 and have now finally gotten around to mounting and installing the new switch.
The switch is made of 4 independent relays that must be wired for proper group operation. The relays are controlled by a small embedded processor with a USB interface.
Since the relays have SMA connectors it is necessary to jumper to some additional SMA to N Female bulkhead adaptors for proper stress relief and cable management.
The final placement, just before wiring. Note the station ground block, this will connect all receivers to station ground system (located near the coax entry area in another room).
Here is screenshot of the software that comes with the switch to control the relays.
Luckily Mini-Circuits includes a DLL that can be used to customize your own application, which is exactly what i did.
