Although the other answers given are correct as best as I can remember from
school (long time ago), for most practical cb or ham radio purposes just
remember that every 3db at a given impedance will 1/2 the power, from radio
to antenna, or antenna to radio.

Hello:

When a table gives the attenuation (at some freq.) for a length of a
particular coax in db,
are they referring to db in voltage or db in power ?

Is is correct to ask a question as simply as the following:

If the attenuation is given as, e.g., 2 db, what Percentage therefore of a
received signal is "lost"
going thru the coax length ?

Thanks,
Bob
