This is simply RX triplexer. There are three band pass filters used as splitters or combiners. Wih very low noise and very good band pass filtering. You can use it as single band signal combiner or as the multiband antenna splitter. For example: You can split beverage RX antenna to 160, 80 and 40m outputs for the antenna switches for one RX on each band. Or you can split single band antennas (vertical array, antenna stacks etc) into one output. All bands are filtred by band pas filters. This output you can use for web based SDR or skimmer server for RBN.

Applications

  • One antenna to more single band RX

  • More antennas to one multiband RX (or more)

  • Web-based SDR, CW/RTTY/FT skimmer for RBN

Splitter

  • There are adapters for F connector version
  • It is than very universal thanks to 50 / 75 Ohm jumper

KIT

Schematic

KIT Assembling

  • Place PCB into the cover of the box

  • Select a few holes and mark tham

  • Carefully dril holes. Use 3mm borer.

  • Mirror the PCB and place it back to the cover.

  • Use screws and nuts to fix it.

  • Carefully dril holes with 3mm and 5,5mm borer.

  • Mount connectors

Transformers

  • There are two binocular ferrites
  • Both have got 2 turns. First with bifilar and second with trifilar winding
  • Clean coating from the ends
  • Place wires in right order like on the pictures
  • Check it again :)

  • Cut all wires to about 210mm (21cm) - 0,69 feet

  • Make bifilar and trifilar wires
  • You can use small PVC tube and AKU drill

  • Assembly all rest parts and transformers
