Hi fellow time-nuts,

For those of you that isn't aware of it, using 75 Ohm antenna cables rather
than 50 Ohm cables is a bad move, as the antenna cable itself will create a
multi-path system. This article elaborate on reflections i cables:

Nothing new, but needs to be said, especially with Thunderbolts getting more
popular, as the manual clearly recommends 75 Ohm cable as I recall it. Do not
listen to that.

Cheers,
Magnus
