Hey guys, thank you for your responces.
Grounding -> I dont think so, dish is up on second floor roof, mounted on the firewall separator (town house). I know it should protect the receiver, but I didnt know it can screw around with the switch.
Installed as following:
110 = diseq 1
118.7/119 = diseq 2 (universal single)
129 = diseq 3
Was hoping I wont have to climb again

but alas it seems I have to go back up!
Cheers,
