!! '''SO2R / Multi operator - with Bi-Dir beverage ''' * There are three switch PCBs in the box. [PICTURE|https://remoteqth.com/img/ZAW/7ant/switch/22_2_940.png] * Each board must be single band. **First, close to connectors is 160m, middle 80m and top 40m. *'''EXAMPLE:''' *There is '''Bi-Dir beverage two coax output antenna on ANT1 and ANT2'''. This antenna needs dummy load for the right work. So ''' ports ANT1 and ANT2 need Jumpers LC-R to LC and dummy load to 50 or 75 Ohm''' *'''OUTPUTs''' are now '''ONLY single band!'''

Jumpers are configured to: '''LC and 50Ohm.''' ** You can see that the antenna port has got good SWR only on 160m. Rest FQ are on High Impedances...
