That could potentially make interference worse!

For a given wattage, lower voltage means higher current which would in turn
generate a stronger magnetic field around the cable.

Low voltage would be much safer though.

10 meteres isnt very far at all and the lighting cables shouldnt generate
much of a magnetic field anyway as the current flowing up one wire would
cancelled by the current flowing back down the other wire.

Losses in the CT100 would be negligable as the LNB output is so high.

If you are running along side a garden path, could you not run power down
one side and comms/data/sat down the other side. Twice as much digging but
it would eliminate any possibility of interference, failing that, just
ensure a few inches separation.
