I just might be able to do that if experiments show that putting the
radio in the house and the whip antenna outside the house works. I
learned something here, namely that the whip antenna serves both FM
and AM. As someone privately emailed me, what better Faraday cage than
a car, so putting a ferrite core antenna in the car wouldn't work any
better than it would in my house. Plus the whip is non-direectional,
an important feature in a turning car.


Even if a radio does have an internal ferrite rod aerial for AM, there
will normally also be a connection for an external AM aerial.

In the old days, it was just along wire strung across the loft space,
or wrapped round the garden.
