It detected aircraft transponders in the 1.09 GHz range.
Here's the text from a couple of ads:
AMBUSH DETECTOR TRACKS POLICE PLANS OVERHEAD --
WARNS YOU WHEN THERE'S A BEAR IN THE AIR!
OVERHEAD SURVEILLANCE -- Your speed is being clocked
from above by a growing fleet of police-owned Cessna 172's
and 182's. They don't use radar (it can't be used from
airplanes), just a simple stopwatch, so your radar detector
won't help. And by the time you notice the tell-tale white
hash marks painted every 1/4 mile along the Interstates,
it's too late! Using aircraft surveillance, troopers
typically quadruple their tickets-per-hour versus radar
(8/hr vs 2/hr!). Ohio alone has a fleet of 10 Cessnas and 3
helicopters, with more on order. And in Florida, 1/4 mi.
markers have been painted on 140 miles of continuous miles
of Interstate. Clearly new technology is need to warn you
of spies in the sky!
A TRACKING COMPUTER -- Spybuster detects aircraft, not
police radar! Highly specialized SMD circuitry operating at
1-2 gigahertz [What I think they mean is that the thingy
receives signals over that frequency range. If, however,
they have built a computer with a clock speed of 2 GHz, I
would like to know more...] receives signals from the FAA's
ground-based aircraft surveillance system. As these signals
reflect off airplanes, Spybuster locates and tracks with
military precision [Well, that isn't saying much is it?
Does anybody recall the precision of the DIVAD?!?] any plane
within a 6 mile radius of your car (scans a full 360 deg.)
[Thanks. I was always confused about how many degrees were
in a complete radius]. With more than one plane in the
area, Spybuster locks on to the closest one (police planes
operate at a low 2000-5000'). It then computes that plane's
closing rate relative to your position, ignoring fast-moving
747's and jet fighters. Since surveillance Cessnas operate
at only 100-140 mph [So, theoretically, I could out run one
if I was going, oh, say 160...], Spybuster warns you
immediately of any plane "loitering" in your area, or
tracking a parallel course. Spybuster is occasionally [sic]
fooled by an innocent civilian aircraft, but has proven
uncannily accurate in identifying police planes before they
get into position to clock your speed!
TARGET RANGE READOUT -- Spybuster's power switch
performs a self-test [Ok. How's it do that? Must be a *BEEP*
complex switch.] and permits muting of the audio alert. The
second green LED is the Tracking Indicator, and lights only
when Spybuster has locked on to a suspect aircraft. [When
will the surface-to-air missile option be available?] The
4-segment Range Readout then flashes in sequence as the
target plane or helicopter closes in. Variable Range
Control lets you set the distance at which Spybuster alerts
you. So when the audio is triggered, and the Range Readout
begins to sequence, there's probably a Bear in the air!

Price: $299
"The SPYBUSTER(TM) is truly a star wars device. Over three years in
design and development by the man who invented the Fuzzbuster(R), it
will do what has been considered impossible...IT WILL DETECT
SURVEILLANCE AIRCRAFT! Now you can defend yourself against this ever
expanding menace."
"The Federal Aviation Administration's new radar system now keeps
track of virtually all aircraft in U.S. airspace. The SPYBUSTER(TM)
utilizes Big Brother's own signals to automatically alert you to the
presence of surveillance aircraft. This unique and highly
sophisticated operating principle makes the SPYBUSTER(TM) effective
and LEGAL throughout the country."
The price of this wonder is $279.95 + $3.00 s&h, and you can order it
from Electrolert, Inc., by calling 1-800-543-3848.
SpyBuster ever saved anyone?
