I recommend that you avoid fancy and expensive antennas that sit on top
of the TV and have lots of knobs and switches -- those are nearly 100%
useless. Begin with what we call "rabbit ears" -- a couple of
telescoping rods in a plastic base which you can adjust in length and
position. That should be adequate to get some TV signals in an area
where the signals are fairly strong. If you have trouble with "ghosts"
(multiple images spaced horizontally), you'll need a directional
antenna, outside or in the attic.

Got a small tv in Luxembourg, no channels found (trying both SECAM and
PAL). I suppose I need an external antenna. Something cheap will likely
do the job as signals should be good in this area, but are there any
pitfalls to avoid in order to avoid a 100% useless antenna?
