RF feeder box

• ONE versions for:
  
  • 1. Variable load resistor - RLOAD
  • 2. Fixed load resistor - RLOAD
  • 3. Easy to set by one JUMPER
• Common-mode coax choke included
• PREAMP with variable gain 0 to 18 dB
• PREAMP Noise Figure less than 2 dB
• Three switchable BPFs or BYPASS
• Front-end RF limiters
• High voltage electrostatic protection with neon lamps
• High power IN/OUT protection with PTC
• Safe to use it close to TX antenna
• Easy to use LAN RJ-45 UTP CAT-6 cable
• F/B depends also on loop installation
  
• Stainless screws and nuts
• High quality connectors
• IP56 box - recommended to protect it against water
• Feeder size 200x150 mm
• ASSEMBLED and TESTED VERSION

Controller

• Universal box for K9AY or 4-way Bi-Dir beverage system - there are BPFs and Preamp only in K9AY++ feeder, not for beverages!
• If you want to use K9AY and 4-way beverage system with BPFs and Preamp, this is better solution K9AY/4-way controller + simply K9AY
• Including Bias Tee AC/DC
• HPF > 100 kHz as AC noise eliminator
• Front End protections
• RF power limiters in RX line
• LED Indicator LOCAL/REMOTE - image
• LED direction indicator 0 or 45 deg. - image
• Rload variable by potentiometer on the front panel
• Three BPFs and Bypass - 4 positions switch on the front panel
• Preamplifier switch and LED indicator
• RX SOURCE switch. Selecting TX or RX antenna for receiving. More info: image and manual

Remote Control Notes

• There is NO IP/web based remote control inside the box. RJ45 connector is only for DC voltage between controller and feeder. Remote Control can be done by the DB15M connector at the rear panel. When you apply +12 to +14 V DC to direction pin at this connector, relay automatically deactivate front panel switches and you can control it over these external voltages at DB-15M Remote Control connector. All LED indicators still work. Please, read the manual.
• We offer now two IP controllers: OLI IP 12 and powerful REMOTIUS 64.

Parameters

• Supply voltage DC (AC for 4-way beverage system) 12 - 14 V up to 2 A

• Bias Tee AC/DC max. 350 mA (for 4-way beverage system)
• HPF > 100 kHz as AC noise eliminator (80 dB at 20 kHz)
• TX power from TRX to TX antenna port up to 400 W
• PTT IN/OUT - only loop, no delay, TX to GND
• PTT logic is 5 V compatible (OM-power)
• Remote Control by external 12 to 14 V DC at remote DB15M
