What does VG2 mean on a radar detector?

Modified on: Thu, 9 Sep, 2021 at 2:48 PM. A VG2 gun is a special device that police can use to identify the presence of a radar detector. It looks like a radar gun, but it does not detect speed. It detects radar detectors. All radio receivers emit a small amount of radio waves.

What is a VG2 alert on a radar detector?

The VG2 alert is the basic technology that allows you to know when the police in your vehicle's vicinity are using radar detector detectors or VG2 systems, to discern whether you are using a radar detector or not.

Do cops use VG2?

It wasn't long before radar detector manufacturers designed their detectors to effectively defeat the VG-2, and nearly all detectors sold today have VG-2 protection. This rendered VG-2 ineffective. It is seldom, if ever, used by police today.

What is the K band on a radar detector?

K band radar are radar waves that fall between 18 GHz and 27 GHz, with most of the law enforcement radar guns operating at 24.125 GHz and 24.15 GHz. Police radar began detecting with K band a few decades after X band was introduced. The biggest problem with the K band is that it leads to a lot of false alerts given.

What does Ka pulse mean on a radar?

The “Ka” on your radar tells you that a frequency commonly used by police enforcement has been detected. A Ka band reading is almost always a police radar, so heed your warning and check your speed.

What K band frequency do police use?

K band radar is the chunk of radar frequency that stretches from 18ghz-27ghz. Luckily for us, police K band radar operates strictly at 24.125 and 24.15ghz. In the law enforcement world, K band radar began to be adopted a couple decades ago as a higher-performance alternative to X band radar.

What sets off K band on radar detector?

Stationary False Alerts

These false alarms come from moving vehicles with advanced safety systems. Some examples of these systems include auto-pilot, radar cruise control, adaptive cruise control and blind spot monitoring systems. These systems emit K band radar signals which will confuse the radar detector.

Do cops use K band?

Police use K band throughout most of the US. Unfortunately there's a lot of other sources of K band besides police radar including speed signs, automatic door openers, and many new vehicles with blind spot monitor (BSM) radar and smart cruise control.

Should I turn K band off?

Unless you live around a relatively wealthy area, and cops are only using Ka bands, you can keep K bands off. However, many places, even older police vehicles use K bands. There is a K band and Ka band filter, keeping K band on might help a little, if not, keep X and K band off.

Who uses Ka band?

Tag: Ka Band

The 30/20 GHz band is used in communications satellites, uplink in either the 27.5 GHz and 31 GHz bands, and high-resolution, close-range targeting radars aboard military airplanes. Some frequencies in this radio band are used for vehicle speed detection by law enforcement.

What happens if a cop sees your radar detector?

Even if the police officer is not targeting your vehicle, your radar detector will detect these electromagnetic signals, and the device will signal to the driver in the form of a bleep or blinking light. If you see the signal, you can release the throttle and hit the brakes to reduce your speed.

Can cops tell if you have a radar jammer?

Not only that, the FCC bans businesses from advertising the jammers in the first place. For most radar jammers police can tell you're using one even if they can't clock your speed. The interference with the radar guns makes it clear and cops can pull you over for it.

Why does my radar detector keep going off?

The most common cause of this is simply that the officer is not operating a radar gun at this time, which means the radar detector has no way to detect the officer's presence.

What is a Spectre alert on a radar detector?

Spectre Alert

It is used by police in areas where radar detectors are illegal to find people who are using radar detectors. Radar detectors with this feature are can detect the Spectre "radar detector-detector" and will alert you when it is detected.

What radar Do police use?

K-band is the most widely used band of radar, not only by the police but also by other sources. K-band is being emitted by automatic doors, security systems, and cars with collision avoidance and lane departure warning. The third band of police radar is called Ka-band.

What K band means?

Definition of K-band

: a segment of the radio spectrum that lies between 10.9 GHz and 36.0 GHz and spans the upper superhigh-frequency and lower extremely-high-frequency bands and that is used especially for police radars, satellite communication, and astronomical observation.

How far can a police radar detect your speed?

Laser guns bounce a narrow beam off a moving vehicle to measure its speed in as little as half a second and up to a mile away. Radar guns use a wider beam to take a measurement in around 3 seconds and up to 300 yards away.

Can a moving police car clock your speed?

Officers spotting a speeding car might follow it, and using an in-car camera system, they are able to record your speed, then pull you over if you've exceeded the limit.

What is a live Ka band?

Live Ka usually means another Live user detected 35.5, 34.7, or 33.8 on their detector recently in the area you are traveling in.

Can a laser pointer set off a radar detector?

Radar detectors

With laser, your radar detector will typically only go off when the officer is targeting you and by then it's too late. By the time it goes off, he's got your speed and your radar detector is little more than a ticket notifier.

What setting should I have my radar detector on?

For the best performance, conventional wisdom says to place the detector as high on the windshield as possible. This may sound like a good idea since radio and TV stations rely on tall towers to broadcast their signals. But police radar doesn't work that way. A visor mount gets the detector up high.
