This is low noise receiveing antenna system for 4 directions in 90 deg angles (can be different, just controller has got LEDs in 90 deg order). 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 from the field to the controller. Controller have got internal PCB with 3 BPFs, preamp and protections. There is also RX ant switch for TRX which does not have input for RX antenna.
Quick Start Guide
Controller
⚠ NOTE: CONTROLLER NEEDS 12-14 V AC POWER SUPPLY!!! NOT DC!
- This controller allows you to control:
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.
- How to prepare it:
- Positions of the antenna in field depends at your possibilities
- If you want to use it in 90 deg cross, than go to next part and select which combination is good for you
- Depends on this configuration you need to select right Jumpers at the Front Panel in the Controller (open enclosure)
- Rear switch at Controller must be switched to 4-way position
- Enjoy your low band DXing :)
⚠ NOTE: There are the common-mode current filters which help you to obtain as low antenna noise as possible. But do not forget to good grounding, not only for antennas but also for 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. More here: link
- 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
Common mode current chokes
- It is recommended to add common-mode current choke filter to the ham shack and do isolation between controller and antenna in field
