[net.auto] Radar jamming and radar detectors

Stuffing steel wool into your hubcaps is a good idea
if your into clean hupcaps on the inside.

If you have an older Corvette, i.e. pre '84, and you have a front license
plate, make sure you angle the plate forward about 30 degrees.  This works
on any car, but is most noticable on the vettes because of their low
radar profile.  Honda civics are also a low profile car.  As for other
cars, Back in 1980 Car and Driver did an article on Radar Range.  They
even found a guy who bought some carbon foam sheets and glued them on the 
hood and front of his Porsche to make it almost invisible to radar.  The
only problem with low profile is that you become more suseptable to the
traffic around you.  For example you come up on a cop about 200 yards
ahead doing 55 mph.  He may not pick you up until 75 yards, but the White
Freightliner behind you can be picked up at 7000 feet!!!  Now if that truck 
is doing 75 mph and he is 1200 feet back and you are in you're nice clean
legal speed but fast looking vette, who do you think will get pulled over?
Before you answer, I'll warn you it depends on the state. In PA, only State
Police operate radar, and they are VERY careful about giving the motorist a 
way out.  They probably would let you and the truck go.  More likely, you
won't see a radar trap in PA where this could occur.  They don't want test
cases in court to go against radar.  In NJ they just nail everybody for
the money, no matter how sure they are, they just want the revenue.

55, it's not just a good idea, it S*CKS


BTW, if enough interest is generated, I'll post some of the information on
how radar guns and jammers work, but it might get lengthy.  As for the 84
vette, I've heard, but not verified, that it is not near as invisible to
radar as the older vettes.

As has already been pointed out, putting steel wool in your
hubcaps won't do anything to reduce the effectiveness of radar.
One thing that could help, however, was mentioned some time ago
in an article in Car and Driver.  They noted that the Corvette
had a particularly low "radar profile" (i.e. could not be accurately
read until the car was fairly close to the radar unit) compared
to other cars and especially larger things like trucks.  They claim
the reason for this is that the Corvette had a slanted radiator
which - being the first reflecting metal in the car - reflected a
fair portion of the radar beams away from the transmitter.  If this
is indeed true, it seems that one could make a metal front for their
car which is at a 45 degree angle to maximize the amount of radar
waves reflected away.  (Of course it would probably look pretty awful
too.)  Is there anyone out there who is familiar with the technical
aspects of radar who could clarify whether Car and Driver's claim
is correct or not and perhaps explain in some detail how radar,
radar detectors, and radar jammers work?

Regarding radar detectors with remote sensors, has anyone tried
hooking more than one remote sensor to the same unit (i.e. one in
the front and one in the back)?  The same article in Car and Driver
indicated that the dash units were effective in detecting both foreward
and rearward radar transmissions (though much less so in the direction
the detector was not facing).  It seems that hiding the sensor behind the
grille would even further limit the rearward range.  (I understand that
the Aston Martin Lagoda is delivered with two Escort units to provide
the same functionality.)

Remember, police radar isn't law enforcement - it's the government
spying on YOU.
