RX Triplexer (2L) as splitter or combiner

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.

Main functions:

• Info:
  • Three Band Pass Filters
  • Low loss
  • More than -35 dB for the neighboring band More with 3BPF board
  • Stackable - more triplexers for more bands
  • Protections
• Works as plitter or combiner
• More single band RX from one antenna Example Example
• More single band antennas to one RX Example Example
• PCB size 100x100 mm
• Available as
  • ASSEMBLED and tested
  • KIT : all parts + PCB
  • PCB only

Use:

• One antenna to more single band RX Example Example
• More antennas to one multiband RX (or more) Example Example
• Web-based SDR, CW/RTTY/FT skimmer for RBN

Versions:

• ASSEMBLED and tested
• KIT: PCB + rest parts
• PCB only

The measured values:

160m, rest open	160m, rest with dummy loads
80m, rest open	80m, rest with dummy loads
40m, rest open	40m, rest with dummy loads
