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.

Quick Start Guide

⚠ NOTE: CONTROLLER NEEDS 12-14 V AC POWER SUPPLY!!! NOT DC!

Controller instructions

This controller allows you to control:

Simply K9AY - link (could be only over coax)
K9AY++ RF box - link (coax + ctrl cable)
Bi-DIR beverage TWO directions - link (only over coax)
Bi-DIR beverage FOUR directions with 4-way switch - link (only over coax)

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. More here: link
