... you would do just as well to add some turns to the ferrite
loopstick for an external antenna and simply shield the radio. That
method
of coupling is very efficient.
In a weak signal area (metal building, basement, etc), any wire that runs
outside can simply be wrapped a few times around the radio and grounded.
The wrapping direction is dictated by the orientation of the internal
loopstick. With a left-to-right loopstick, you wrap over the top and bottom
When I was in the Navy, I liked having a bedside radio, so that was my
method. On one ship, I was near a door to an open deck, so I snaked a wire
outside and strung about 30 feet of it behind a pipe. On another ship, I
connected my wire through a cap to the telephone wire. I got a lot of
click/pop noise on that one but I had a half-dozen AM stations I could hear
OK.
Best reception job was on a carrier. The "weather-guessers" were high up,
on the 07 level and I ran a cable to my office on the 02 level. They had
their own WEFAX whip antenna feeding an antenna filter panel (AN/SRA-12, if
you know what that is.) They didn't use the BCB output of the filter panel
(but I did). It's good to be the Department Leading Chief.
