How far away is your other antenna?

2.4 GHz signals may be attenuated by up to 0.05 dB/km (0.08 dB/mile) by torrential rain (4 inches/hr). Thick fog produces up to 0.02 dB/km (0.03 dB/mile) attenuation. At 5.8 GHz, torrential rain may produce up to 0.5 dB/km (0.8 dB/mile) attenuation, and thick fog up to 0.07 dB/km (0.11 dB/mile). Even though rain itself does not cause major propagation problems, rain will collect on the leaves of trees and will produce attenuation until it evaporates.

Foggy windows can be dangerous at night

Ever find yourself dealing with the windows fogging intensley during the day or night while raining or just other extreme weather conditions that come your way?
A real good product to use for this is called "Rain X", buy it at any major auto parts dept. apply to your windows prior to traveling, as per directions, and walla no more fogging.
Happy Motoring!!

Windscreen keeps misting when car is parked

Is it fogging up when you use the heat or a/c? Is it fogging up after sitting outside on a particularly dewey night?

An easy fix and one to try first is turning the temperature gauge over toward heat, and setting the directional controls to defrost. Up the power on the blower for a moment. The warmer air will usually clear up a foggy windshield in seconds on a chilly or even not-so-chilly morning. The condensation on the glass needs a change of temp in order to evaporate. Sometimes you can get the same effect by using outside air to circulate through your car's blower system. Most have a way of circulating either inside-car air, or outside-car air.

If the glass fogs when you're driving down the road and have the heat on, or the a/c - do you smell something sweet or see white smoke coming out of your air vents? If so, you could have a faulty heater core. I wouldn't imagine this is the problem on such a new vehicle, but it could still malfunction.

Of course, if you're trying to wipe this fog clean and it won't go away, maybe you've got someone smoking in the car and leaving a film on the glass. It would take a lot of smoking to make the windshield look foggy though.

The outer bulbs may not be used in your vehicle's application. Sometimes VW's and other European vehicles are equipped with rear lights that are used in foggy weather. They will come on when the fog lamps are activated and the switch on the dash will give the driver the option to turn on the right one or the left one depending on whether you are in a country that has left hand driving or right hand driving. The lights are there for "parking purposes" so that the vehicle can be seen in extreme fog conditions when parked on the street. If the vehicle isn't equipped with the system, the taillights may have provisions for it anyway.

My windscreen becomes foggy in no time as soon as I start driving in cold weather?

if the fog is on the inside of windshield and does not feel oily i would look for a water leak into the heater asm or the vehicle. if moisture on windshield is oily,then the heater core maybe the cause due to a leak.
good luck! check UNDER the carpets for water!!

The foggy images and lens was due to condensation caused by the camera's surfaces being cold in a humid/moist environment. Usually this happens and goes away without issue. If you believe issues are continuing, consider placing the camera completely in a bowl of uncooked rice. The rice should help eliminate the moisture in the camera.
Hope this helps.

The Intel® Desktop Board D845GVAD2 supports a single Pentium® 4 processor with a system bus frequency of 400 MHz or 533 MHz, or a single Celeron® processor with a system bus frequency of 400 MHz.

So you can install upto 3.06 GHz 533 MHz(cache memory) processor and also update the ram 2 GB 400 mhz.
Dont install Prescott processor.
Hope it will help you.

MOST DJ lights are not protected to be used outside in weather.

Other considerations are visibility from highways and also aircraft. Certain lights could cause a problem for these two scenarios.

When outside, often the distances are longer and the light drops off as the square of the distance.

Laser types require fog to get the effect and there really isn't a way short of getting the weather to cooperate and give you fog to get those effects.

Between the laws of physics and the construction of lighting intended for interior use, what you are asking for is just not easily obtained.

The inability to control ambient lighting outside is a real problem. Many of the DJ things require a fairly darkened room. The sky glow from a city is enough to kill off the effects.
