Description

This antenna consists of 2x Bi-dir beverage sets, 4-way switch and K9AY/4-way controller. That all allows you to have 4 directions beverage antenna system with only one coax line from field to the controller. Controller have got Bias Tee (AC/DC), HPF (kill AC noise), internal PCB with 3 BPFs, preamp and protections. There is also RX/TX RF switch for TRX which does not have input for RX antenna.


Main functions

  • Low noise RX antenna system
  • Broadband 0.1 to 30 MHz
  • 4 directions beverage/K9AY
  • Small room for K9AY, larger for beverages
  • 50/75 Ohm feed line tolerant
  • Built-in Bias Tee AC/DC
  • PREAMP with variable gain 0 to 18 dB
  • Three switchable BPFs or BYPASS
  • RX protections and limiters in controller
  • RX source switch for TX and RX antenna

Controller

  • Universal box for K9AY or 4-way Bi-Dir beverage system - front panel image
  • 4-way beverage system can have 4 construction positions in the field - more info in manual
  • FOUR direction switch
  • Including Bias Tee AC/DC for RX antenna
  • HPF > 100 kHz as AC noise eliminator (80 dB at 20 kHz)
  • Front End protections
  • RF power limiters in RX line
  • LED Indicator LOCAL/REMOTE - image
  • LED direction indicator 0 or 45 deg. - image
  • Three BPFs and Bypass - 4 positions switch on the front panel
  • Internal PCB with BPFs and preamp
  • RX SOURCE switch - selecting TX or RX antenna for receiving - More info: image and manual
  • Preamplifier switch and LED indicator
  • POWER SUPPLY MUST BE 12V AC not DC
  • SMD + THT construction
  • Stainless screws and nuts
  • High quality connectors
  • ASSEMBLED VERSION

Bi-directional beverage antenna ONE coax output
