Description

This is universal antenna, filters or TRX switch. Version MK2 with higher isolation and new hazard protection board. There are also BCD inputs with optocoupler isolators, high voltage protection and BCD is compatible with TTL logic and up to 15 V DC. BCD data with voltage more than 13 V DC could directly supply relays.


Main functions

  • Six ports switchable to two inputs/outputs
  • Frequency range DC-60 MHz
  • Characteristic impedance 50 Ohm
  • High isolation and low insertion loss
  • Power rating DC to 30 MHz
    • 3 kW continue wave
    • 4 kW PEP (SWR < 1:1.7) - tested with OM-4000
  • Control positive DC 2 x 6 or 2 x BCD
  • Hazzard board protection with 2 x 6 and BCD inputs
  • First-Win logic
  • Without DC power the antenna ports are grounded
  • High quality RF PCB thickness 2 mm
  • High quality connectors
  • Aluminium shield enclosure
  • Aluminium mounting holder with bracket - pipe max 52mm
  • AL box size 222x145x75 mm
  • ASSEMBLED VERSION

Parameters

  • Frequency range DC-60 MHz
  • RF power up to 4 kW
  • High isolation between A and B ports: 100dB (20m), >90dB (10m) - no port selected
  • High isolation A-1 and B-2: >100dB (80m), >84dB (20m), >74dB (10m), 64dB (6m)
  • High isolation A-4 and B-1: >100dB (80m), >87dB (20m), >77dB (10m), 67dB (6m)
  • Insertion loss better than 0.04dB (10m), 0.02dB (20m)
  • Control DC 2 x 6 wires + 12 to 15 V or image
  • Control 2 x BCD + 3 to 15 V (TTL compatible or direct 13 to 15 V BCD) image
  • When the BCD voltage is higher than 13 V, it directly supplies the relay
  • BCD inputs with optocouplers and protections
  • BCD inputs wide range 3 to 15 V DC
  • BCD inputs with positive control compatible with OM-power, Microham. Pull up for open collector - image

Isolation example

  • TRX A output power 1kW = 60dBm
  • Isolation to port B is 80dB → 60dBm - 80dB = -20dBm
  • ~ 10uW at TRX port B

DO NOT forget to

  • Isolation between antennas!
  • The safe power isolation is not only about the switch isolation!
  • Never switch relay during TX!

Connection

  • You can use 2 x 6 + GND = 13 wires (12 to 15 V DC)
  • You can use 2 x BCD (TTL) + GND + 13.8 V = 8 wires
  • You can use 2 x BCD (> 13 V) + GND = 7 wires

  Third party software FreqEZ

FreqEZ is a Do-It-Yourself hardware/software project by Larry K8UT that provides highly configurable Band Decoding and Remote Antenna Selection. For amateurs who use N1MM+ and DXLab logging software, FreqEZ will leverage those programs TCP/UDP broadcasts for antenna switching. For other amateurs, FreqEZ can connect to the BCD band outputs available from most transceivers. The FreqEZ software and is freely available to all hams, and consists of a pair of programs that run on the Windows and Raspberry Pi Raspbian operating systems.
