Switching antennas with AMERITRON-RCS10, no matter which position, they all have the same signal strength I had imagined that this is what a long winter pass is like, but when I checked it with a tester, the control wire was broken! I re-bought the wire and rewired it, but I made a bit of an idea modification with Lotlot lessons!
Three LEDs are installed in the box, so that you can see if the relay is working reliably without using a tester.
A simple universal board with LED and 1K Ohm resistor. LAN cable connector also installed for easy removal of the lid
It's nighttime and the LEDs change with BCD when you move the selector in the room Now you can visually check the condition of the cables.
