This 4-way Beverage antenna system consists of two Bi-dir Beverage sets, 2-way RX antenna switch and controller. That all allows to have 4 directions Beverage or/and K9AY antenna system with only one coax line from field to the controller. Controller have got internal PCB with 3 BPFs, preamp and protections. There is also RX antenna switch for TRX which does not have input for RX antenna. You can also connect an external IP module to control the entire system remotely.

Product details

Step by step

• - Select the appropriate Beverage Antenna design. Here it depends on your possibilities and space. Result: the classic antenna in the air design gives a stronger signal but needs more space.
• - You can also add a K9AY, which does not need a large space.
• - You can combine Classic and BOG, but you have to count with different signal and noise levels - it can be annoying. You can compensate by reducing the RF-Gain on RX and using Volume, for example.
• - Avoiding bringing RX antenna close to other masts and vertical antennas. Also, installing a Beverage antenna over a metal fence is not a good way to go.
• - Connect the Bi-DIR Beverage antennas to the 2-WAY RX switch with a coaxial cable.
• - Set the 2-WAY RX switch to control with - DC and turn on AC/DC Pass.
• - Connect the 2-WAY RX switch to the controller with a coaxial cable.
• - Set the correct jumper configuration inside the controller to match the location of your antennas - direction, LED indication, etc.
• - Put the switch on the back panel of the K9AY/4-WAY in the correct position: which antenna you want to control.
• - You can add one more 2-WAY RX switch to use both, 4-way Beverage and K9AY.
• - Connect the 12 V AC power supply.
• - Test.
• - Go do DX :)

⚠ There are the common-mode current filters which help you to obtain as low antenna noise as possible. But NOT forget to good grounding, DO NOT only for antennas but also for 2-way (4-way) switch.

Controller - manual page

This K9AY/4-way antenna switch allows you to control:

• simply K9AY (could be only over coax)
• K9AY++ RF box (coax + ctrl cable)
• Bi-dir beverage TWO directions (only over coax)
• Bi-dir beverage FOUR directions with 2-way (4-way) switch (only over coax)
• Remote Control
• Band Pass Filters
• Preamplifier
• RX Source switch
• You can use some features for more RX antennas.

You have to setup:

• Internal jumpers for LED (N or NE)
• Internal jumpers for Bi-DIR Beverage position-directions
• You can enable K9AY control over the coax
• More in the manual for Controller

TIP - when you want to use Beverages and K9AY:

There is a small toggle switch on the rear panel that toggles the Beverage and K9AY controls. If you want to operate both antennas, this switch is inconvenient. You can therefore attach an external switch and place it in a better location.

Connect this switch to D-SUB connector REMOTE between pin 15 and 4. More at manual

2-way RX switch box - manual page

This switch is controlled by the voltage on the coaxial cable or by voltage at internal socket. It also includes dummy loads and a common mode filter.

This switch can install it as a middle switch for two Bi-DIR Beverage Antennas or as a switch between 2-way Beverage and K9AY.

It's all about the internal jumper settings.

Example with two 2-WAY RX switches: direction and Beverage/K9AY

You have to setup for 4-WAY Beverages:

• Internal jumpers JP2 to Coax
• Internal jumpers JP3 to - DC
• Internal jumper JP1 to right position

Adding K9AY simply feeder - product page

Possibility to add K9AY antenna to Beverage system. With this option you get 4 more directions with very different radiation angles. You need to add an RF switch between the Beverage system and the K9AY, enable the K9AY control in the controller and set the jumpers in the K9AY feeder correctly.

You have to setup - 2-WAY RX switch between controller, Bverages and K9AY:

• Internal jumpers JP2 to EXT
• Internal jumpers JP3 to + DC
• Internal jumpers JP1 to right position
• You have to connect 2 wires from controller to J3

Connect GND and PIN 11 at D-SUB connector ACC TO RELAY at controller to VEXT and GND J3 connector in 2-WAY RX switch.

Now the rear toggle switch control this RX switch between 4-WAY Beverage and K9AY – or external, see text.

You have to setup - Controller:

• Enable K9AY control over the coax JP5

You have to setup - K9AY simply feeder:

• Short JP3
• Select JP4 to Coax
• More at manual

Bi-directional Beverage antenna ONE coax output - manual page

2 pairs of Bi-dir beverage set (2x feeder box and 2x terminator box)

Where are your feeders? Direction matrix

This configuration is very important. Although beverage antennas can be placed in different ways, the control voltage remains the same. Therefore, the jumpers in the controller must be interconnected. This ensures that the direction indicator corresponds to the correct routing of the antennas.

• Everyone has different antenna configuration and also feeders could be on different places
• Controller allows you to set right jumpers and follows your installation - more info in article
• There are all 4 combinations
• Where there are terminators and feeders (Bi-directional beverage)
• Short jumpers for right 4-way Bi-dir beverage orientation - more info in article

Options: Recommendation to buy

• It is recommended to add common-mode current choke filter to the ham shack and do isolation between controller and antenna in field
  
• You can buy also D-SUB 15 female 1m cable or D-SUB screw terminal
• Good option is also power supply 13.8 V 30 A analog or digital version
