To power up your Relay box and enable multiband operation you need to hook up a control cable. Six
conductor cable is ideal for this. Attach one conductor to each stud on the isolator unit. These lines carry 12 volts
d. c. with very little current, typically 50 ma. The studs on the isolator unit are marked 20m, 17m, 15m, 12m, 10m
and C.
5)
The rear of the Super “C” switch box is also marked 20m, 17m, 15m, 12m, 10m and C. You can use just
about any wire to run from the antenna isolator to the switch box at your station. If you use color coded wires
attachment will be easier. Make sure that the wire you attach to the stud on the isolator is attached to the
corresponding terminal on the Super “C” switch box. 10m to 10m, C to C, etc...
6)
The Super “C” switch box requires 12 v dc nominal. It can be obtained from your transceiver’s power supply
or from any other 12 vdc source such as a wall transformer. 12 vdc “+” and “-“ terminals are provided at the rear
of the switch box.
7)
If the led on the front panel is lit, you know that the required 12 volts dc is being supplied. Band selection is
simple, simply rotate the band selector switch on the switch box to the band you wish to operate. When the led on
the front panel lights 12 vdc is available and the relays are being energized.

7.0 Final Check - Out
1)
It is suggested that you position the Super “C” where it can be easily reached for testing. Once check out is
successfully completed you can move the Super “C” to its final location, which should be inaccessible to human or
animal contact.
2)
Connect your transceiver to the antenna using 50 ohm coax of the length you expect to use in the Super “C”’s
final location.. Apply 12vdc power to the switch box via your power source.
3)
Set the band switch on the switch box to the 20 meter position.. Observe that the yellow LED is lit. If not
check to make sure the 12vdc power supply is turned on or if you are using a wall unit that the unit is plugged into
the wall socket. Switch the band select switch to “off” and note the LED turns “off.” Return to 20 meters. Set
the transmitter to 20 meters. Apply R.F. power to the antenna and measure VSWR. Vary the frequency to obtain
