Automatic Antenna Switch Circuit using LM3914 -An automatic antenna switch circuit diagram is shown in the following schematic.
It uses the LM3914 integrated circuit which the output is used to activate transistors as switches to provide 12V DC for the remote coax relays.
This automatic antenna switch circuit requires MPS2907 transistors, LM3014 IC, 5mm 10mA @2V LEDs, 1N914 diodes, all 1/4 Watt 5% resistors and disc ceramic capacitors.
Or you might need the LM3914 datasheet (source: national.com)
