6-to-2 antenna switch MK2 CLASSIC

6-to-2 antenna switch MK2 CLASSIC

This is high isolation, low loss 6 to 2 RF switch.

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

Available as

ASSEMBLED: ready to use
Connectors: PL SO-239 or N

ℹ 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.

This antenna switch can be controlled by our 6-2 Easy Controller
