Band data pinout at Yaesu Mini-DIN8 band data connector.

I don’t offer the cable between transceiver and the Band Decoder. For the transceivers with

the Mini-DIN8 you can buy standard Yaesu CT-58 cable, for the transceivers with the DIN8

search the Web and eBay. Those cables are available from other sellers.

The antenna switch relays are connected via K1-K5 terminal blocks. Do not forget to connect

also the power ground from K5.2.

Applications

With the Band Decoder you can control up to 9 separate relays one for each band.

Very often many Hams use multiband antennas and then less amount of relays are needed.

In this case you can combine the Band Decoder outputs in parallel.

Examples:

1. You have 4:1 antenna switch and 4 antennas, but only 2 are mono-band antennas.

20m 5 band Yagi 4 K3.1+K3.2+K4.1+K4.2+K5.1

17m 5 band Yagi 4 K3.1+K3.2+K4.1+K4.2+K5.1

15m 5 band Yagi 4 K3.1+K3.2+K4.1+K4.2+K5.1

12m 5 band Yagi 4 K3.1+K3.2+K4.1+K4.2+K5.1

10m 5 band Yagi 4 K3.1+K3.2+K4.1+K4.2+K5.1

The Band Decoder outputs can be combined at the PCB with short wires or at the terminal

block. See images.
