These are normally built on request and will have a lead-time of about 2-3 weeks. Sometimes they might be in stock which can be seen in the stock status.

The 6×2 is an antenna switch which can route 6 antennas to 2 radios. The switch consist of two PCBs, one which is for the RF part that route the actual antennas to the radios and one board which contains a bunch of relays which used to interlock the radios in a fashion that first wins. So if for example radio 1 has selected antenna 5 and radio 2 tries to select it nothing will happen. The RF board is also designed in such a way with three relays per antenna port making it impossible if the interlock for some reason fails to actually connect radio 1 and radio 2 together. The extra relay also increases the isolation between the ports.

The box is precision CNC milled with the text engraved so that there is no risk that the markings of the ports will disappear because of UV-light. The boxes are powder coated black with IP65 rating and have a vent which helps to keep moisture away. All connectors have PTFE (teflon) insulation. All switches have been developed with high end network analyzers that give reliable results.

The device uses positive switching, which means all the relays use common ground. So to enable an antenna you would add a voltage of +12V on the control line. 2×7 leads are needed to control the box, so a couple of network cables are perfect to switch it. No control box is included.

Isolation (Depending on port, between R1 and R2)
50 MHz: -57 to -70dB
28 MHz: -61dB to -80dB
14 MHz: -68dB to -85dB
3.5 MHz: -85dB to -100dB

Typical insertion loss 1.8 – 28 MHz < -0.06 dB
Typical insertion loss 50 MHz < -0.10 dB

Typical VSWR 1.8 – 28 MHz < 1.15:1
Typical VSWR 50 MHz < 1.3:1

Power rating (1.8-30 MHz, SWR <1.3:1) 5kW
Power rating (1.8-30 MHz, SWR <2:1) 2.5kW
Power rating (1.8-30 MHz, SWR <3:1) 1.5kW
Power rating 50 MHz 2.5kW


It is also recommended that you think through were to put the antennas on which port. As can be seen in the measurements you will typically depending on the compensation coil have lower insertion loss on port 1 and less good high frequency performance on port 6. This is because of the coil being an average solution over the frequency range. Also there is always less isolation between two adjacent antenna ports. So if you have antennas closed spaced on certain bands it might be a good idea to separate them with at least one antenna port between.  Remember that even such a low increase in isolation as 3dB will be the same as you dropping your power in half.
