!Single Operator 2 RX (SO2R) / Multi Operator 2 RX - without Bi-Dir beverage *There are two switch PCBs in the box. [PICTURE|https://remoteqth.com/img/ZAW/7ant/switch/IMG_5411_web_2.png] *There is '''NO antenna''' which needs dummy load for the right work. So '''all ports can stay OPEN = Jumpers LC-R are OPEN.''' *'''All OUTPUTs''' are ALL bands so you can use controllers on ALL bands too. '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} Do not use controllers on THE SAME band. This is not recommended - use two switches and middle splitter.'''

[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!''' '''{.redka#id color: #f23f37; font-size: 200%}⚠{/} Follow the band lables under connectors outputs on the box.'''

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...
