Default coils : turns shorted = quality ?

HI,

Often I can see coils where some turns are shorted in order to modify
there value.
I wonder whether these shorted turns would not be seen as a short cicuit
and could decrease the quality of that coil.
How can I have an idea of the lost of quality without complex equipment ?
I plan to build this kind of coil for a shortened antenna...

regards

Good question! I've always wondered about that too. In a former life as a
marine electronics technician, the old marine "AM" transmitter antenna
tuners uses shorted turns a lot. It always sort of went against the grain, I
thought, but in practice, it seemed to work ok. What was I missing here?
