This is low noise receiveing antenna system for 4 directions in 90 deg angles.
This antenna consists of 2 x Bi-dir beverage sets, 4-way antenna switch and controller. That all allows you to have 4 directions beverage system with only one coax line to the controller. Controller could have internal optional PCB with 3 BPFs, preamp and protections. There is also RX ant switch for TRX which does not have input for RX antenna.

⚠ NOTE: CONTROLLER NEEDS 12-14 V AC POWER SUPPLY!!! NOT DC!
How to connect it
- There are two Bi-dir beverages in the field.
- You can place this pairs as you need.
- The example is in 90deg, than you can RX signals from 45, 135, 225 and 315 deg.
- You need one coax from the each Bi-dir beverage antenna.
- coaxial cables go to middle 4-way (4 direction) switch.
- Than only one coax goes to the controller.
⚠ NOTE: There are the common mode current filters which help you to obtain as low noise antenna as possible. But do not forget to good grounding, not only antennas but also 4-way switch.
Where are your feeders
- Everyone has different antenna configuration and also feeders could be on different places.
- Controller allows you to set right Jumpers (JP) and follows your instalation.
- Thare are all 4 combinations
- Where there are Terminators and Feeders (Bi-directional beverage).
- SHORT jumpers for right 4-way Bi-DIR beverage orientation. More here: link
