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 90 deg, then you can receive 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
  • Then only one coax goes to the controller
  • How to prepare it:
  • positions of the antenna in fields depends at your possibilities
  • it you want to use it in 90 deg cross, then 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 :)

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




Where are your feeders? Direction matrix

  • 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
