If you are using an Icom transceiver and have only two antennas, one antenna for higher bands and another for lower bands, this antenna switch might be good for you.
This ASW2 antenna switch is capable to handle legal QRO power.
JUMA ASW2 antenna switch for low/high band selection for Icom.
It is using Icom band voltage from ACC connector. The lower band threshold
can be selected by the jumper to 160m, 80m or 40m. The LEDs are indicating
which one of the two antennas is in use.
Only 3 wires is needed to connect to Icom. Although ASW2 is RFI tolerant, it recommended to use a shielded cable from Icom ACC to ASW2 DB9 connector. See your Icom ACC connector pin order and the schematics for wiring details. Check carefully the supply polarity, + for pin8 and GND for pin2 in the DB9 connector. |
