Really? Um in good signal areas it does but near to big buildings and hills
I notice that they tend to descend into boiling mud mode then switch to
another station.
With fm its the his and multipath distortion and weird whistles and
burbles that go up and down, often going back to mono gradually or abruptly
depending one supposes on the receiver design.

I ride in a lot of private hire cars and notice such things.
Very few have traditional aerials, many have the rubber duck and some
still use window heater aerials.

How do these work if only a 6 inch stub sticks out of the roof ?

To get a decent FM signal indoors I need a dipole of some sort
that is about 59 inches long, plus reflector and director.

I ask this because I am getting interference on 88.50 Mhz
from Rowridge, but not all the time. Earlier today it
was bad, but the other BBC FM stations were not affected.

When I drove into town, FM R2 on my car radio was fine,
but I don't know what transmitter it is picking up. No
interference at all. Strange.

I am midway between IOW and Wrotham.

Poorly is how they perform. Much better to have a telescopic antenna
that rises to about a quarter wave (75 cm). If you live in a poor
signal area with interfering transmitters coming in, a directional
antenna is the only answer, and you can't have that on a car.

How about DAB? That works 100% better than FM in a car.
