Awl-- (also posted to rra.antenna)

I had long noticed much superior tuning in car radios over my home radios.
Several apparently knowledgeable people on a few radio ngs confirmed this,
even explained it, altho this went over my head.


*Finally* accomplished said task, and, big big bummer, the reception of the
car radio in my shop/garage is even worse than my home radios/stereos!
Yet, this *same radio*, when I used to park the car this very same garage,
had great reception.

Whazzup????

Your on the right track OK - dont give up. Car radios ARE better,
their designed to operate on crappy aerials in a noisy environment.
BUT, they are optimised for the car type aerial - wont go into the
physics. As an starting point,can you plug in a car antenna, even if
it needs getting an extension lead to get it outside and into clear
space? - the leads are available from car stereo places, come with all
the correct plugs/sockets, and (usually) some extra capacitance to
match into the car antenna.....

Let us know how you get on, its a worthwhile project....

It is funny how a car antenna is vertical, when most dipoles are horizontal.
Anyway, I have a car antenna floating around I could use.
In the meantime, I dropped two conductor wire from my top window, about 40
feet up.
THAT oughtta get some kind of signal. Unfortunately, it's mostly vertical,
would like to get some of it horizontal--assuming that would help.

Discussions off-line are pointing me to a good log-periodic antenna, on top
of a big-assed tree, rotatable.

If *that* don't work, I guess I'm just gonna have to start whistling old
tunes.

It would be even funnier to see a horizontally-polarized antenna on a
cargrin! (actually, I have one - for the 144MHz ham radio band)

Nearly all AM/MW stations use vertical transmitting antennas, not that
matching polarization is particularly important in that band.

In the U.S., the vast majority of FM stations use both
horizontal *and* vertical polarization (I think they call that "mixed
polarization" overseas) so a vertically-polarized car antenna works just
fine.

I don't think it'll make much difference.

I believe they actually use circular polarization, so there's a 3dB loss when
received by a linearly polarized antenna. Still, I'm told this is almost
always a huge improvement over what you get with the transmitter and receiver
both using linearly polaraized antennas.

I don't think it'll make much difference.

I agree. In fact, as far as I've seen, unless you're running high gain
point-to-point links, it doesn't seem that matching antenna polarizations on
both ends matters all that much, since the fields will tends to have become
randomly polarized as they propagate and reflect anyway. (Of course, I figure
one of the much more experienced people here can correct me on this if need
be!)
