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).

Applications

- Bi-Dir beverages array with four directions over one coax
- Two port switch controlled by the negative voltage over coax

example with Bias tee and Bi-dir antennas

example of antenna configuration - 4-way beverage system

version with PL SO-239 connectors

version with F connectors

version with N connectors

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
