This is two port antenna switch - middle box between pair of Bi-Directional antennas with single coax output.
4-way switch for Bi-directional beverages manual
This is two port antenna switch - middle box between pair of Bi-directional antennas with single coax output. It allows you to control ALL 4 directions over one coax cable. Directions are controlled by the voltage over the coax (0, +12V, -12V and AC).

PCB
KIT Assembling
version with PL SO-239 connectors
version with F connectors
- Use right resistor (for 50 Ohm coax line use 100R/2W and for 75 Ohm coax line use 150R/2W
- Place LED diode in right polarity (longer leg is + and is connected to GND on PCB)
- You can use Glue gun to fix F connector
